The Illumina NovaSeq 6000 Integration Package v2.6 supports the integration of Clarity LIMS to NovaSeq 6000 instruments.
This document describes the integration and includes information about the preconfigured protocols, steps, automations, installed components, configuration requirements, rules, and constraints.
The configuration provided in this integration has been established to support NovaSeq 6000 lab processes. Any configuration changes to protocols or workflows—including renaming protocols, steps, and fields—could break the process.
Prerequisites and Assumptions
It is assumed that samples enter the NovaSeq 6000 v2.3 workflow as normalized libraries. That is, before they are assigned to the workflow the following actions occur:
Samples have been accessioned into Clarity LIMS.
Samples have been run through QC and library prep.
Samples have been normalized, and the value is captured in a field called Normalized Molarity (nM).
Included for validation purposes only, this protocol models the library prep steps required to advance samples to the Run Format (NovaSeq 6000 v2.3) protocol.
The protocol contains a single step: NovaSeq Validation Library Prep (NovaSeq 6000 v2.3). At the end of this step, a routing script sends the samples to the first step of the NovaSeq 6000 v2.3 workflow, which is Define Run Format (NovaSeq 6000 v2.3).
Allows for the assignment of per sample values for Loading Workflow Type, Normalized Molarity, Flowcell Type, and Final Loading Concentration (pM).
Loading Workflow Type: Select from NovaSeq Standard or NovaSeq Xp.
Normalized Molarity: Enter a value for each sample.
Flowcell Type: Select from options S1, S2, S4, and SP.
Final Loading Concentration (pM): Select from the options 225 (PCR-free workflows) or 400 (Nano workflows). Alternatively, enter a different value.
Compares the Normalized Molarity value of each sample with the Minimum Molarity value.
Routing script sends samples to the NovaSeq Standard or NovaSeq Xp protocol, according to the selected Loading Workflow Type. Samples with Normalized Molarity less than Minimum Molarity are removed from the workflow.
Steps:
Define Run Format (NovaSeq 6000 v2.3)
Protocol 2: NovaSeq Standard (NovaSeq 6000 v2.3)
Purpose:
Samples are pooled and added to the library tube in preparation for the NovaSeq run. Sample sheet and run recipe files are generated.
Routing script sends library tube to the AUTOMATED - NovaSeq Run (NovaSeq 6000 v2.3) protocol.
Steps:
Make Bulk Pool for NovaSeq Standard (NovaSeq 6000 v2.3)
Dilute and Denature (NovaSeq 6000 v2.3)
Protocol 3: NovaSeq Xp (NovaSeq 6000 v2.3)
Purpose:
Samples are pooled and added to lanes on the NovaSeq flow cell. The flow cell type is determined by the option selected in the Define Run Format (NovaSeq 6000 v2.3) step. Sample sheet and run recipe files are generated.
Samples are queued for the AUTOMATED - NovaSeq Run (NovaSeq 6000 v2.3) protocol.
Steps:
Make Bulk Pool for NovaSeq Xp (NovaSeq 6000 v2.3)
Dilute, Denature & ExAmp (NovaSeq 6000 v2.3)
Load to Flowcell (NovaSeq 6000 v2.3)
Protocol 4: AUTOMATED - NovaSeq Run (NovaSeq6000 v2.3)
Purpose:
All samples complete the workflow by going through this protocol.
This protocol contains one fully automated step.
⚠ Do not add samples to the Ice Bucket or start the step. The integration does this action automatically.
This protocol sets the Loading Workflow Type and allows you to choose the appropriate Flowcell Type and Final Loading Concentration(pM). At the end of the protocol, a routing script sends the normalized libraries to either the NovaSeq Standard (NovaSeq 6000 v2.3) or the NovaSeq Xp (NovaSeq 6000 v2.3) protocol.
This protocol contains one step: Define Run Format (NovaSeq 6000 v2.3).
Step 1: Define Run Format (NovaSeq 6000 v2.3)
Step input: NTP (normalized libraries)
Step output: None
Set Next Steps Automation
Automatically triggered on exit of the Record Details screen, this automation does the following actions:
Sets the next step for samples to REMOVE with
nextStep = ::REMOVE::
Calculates the Minimum Molarity using the following formula:
Checks Normalized Molarity value. For samples with no Normalized Molarity value (e.g., an empty value, not including 0), the automation generates an error message stating that the field cannot be empty:
if (!input.hasValue(::Normalized Molarity (nM)::)) { fail(::The Normalized Molarity cannot be empty.::) ; }
Compares the Normalized Molarity value of each sample with the Minimum Molarity value. If Normalized Molarity value is lower than the Minimum Molarity value, sets the Loading Workflow Type of the sample to [Remove from workflow] and records a message in the Warning field:
else if (input.::Normalized Molarity (nM):: < input.::Minimum Molarity (nM)::) { input.::Warning:: = ::The Normalized Molarity is too low.:: ; input.::Loading Workflow Type:: = ::[Remove from workflow]:: ; } else { input.::Warning:: = ::n/a:: }
At this point, there are two options:
Correct the Normalized Molarity value on the Record Details screen. Also, edit the Loading Workflow Type field and set it to NovaSeq Standard or NovaSeq Xp, as applicable.
Complete the protocol without correcting the Normalized Molarity value. In this case, those samples are removed from the workflow.
Routing Script Automation
Automatically triggered on exit of the step, this automation invokes the changeWorkflow script, which routes step inputs appropriately.
Samples with Loading Workflow Type field value of NovaSeq Standard are routed to the NovaSeq 6000 v2.3 workflow and queued for the Make Bulk Pool for NovaSeq Standard (NovaSeq 6000 v2.3) step.
Samples with Loading Workflow Type field value of NovaSeq Xp are routed to the NovaSeq 6000 v2.3 workflow and queued for the Make Bulk Pool for NovaSeq Xp (NovaSeq 6000 v2.3) step.
The default automation command line is as follows.

Protocol 2: NovaSeq Standard (NovaSeq 6000 v2.3)
Samples are routed to this protocol if the Loading Workflow Type value is set to NovaSeq Standard. Samples are pooled and added to a library tube in preparation for the NovaSeq run.
At the end of this protocol, a routing script sends the library tube to the AUTOMATED - NovaSeq Run (NovaSeq 6000 v2.3) protocol.
This protocol contains two steps:
Make Bulk Pool for NovaSeq Standard (NovaSeq 6000 v2.3)
Dilute and Denature (NovaSeq 6000 v2.3)
Step 1: Make Bulk Pool for NovaSeq Standard (NovaSeq 6000 v2.3)
In this step, manually place libraries into a single pool. Resuspension buffer and reagents are added.
Only create one pool per step.
Step input: NTP (normalized libraries)
Step output: Bulk pool
The following automations are configured on the step (in the order they are triggered at run time).
Validate Inputs Flowcell Type and Single Pool Automation
Automatically triggered on exit of the Pooling screen, this automation checks the following information:
All samples in the pool have the same Flowcell Type assigned to them.
Due to the 4000-character limit, part of the script definition of Calculate Volumes has been moved into the Calculate Volumes Script field. If this part of the script needs to be modified, you can make the changes to the default value of the Calculate Volumes Script field. The parts of the script that were moved into the Calculate Volumes Script field are identified below.
Automatically triggered when the Calculate Volumes button on the Record Details screen is selected, this automation does the following actions:
Calculates the number of samples in the pool:
step.::Number of Samples in Pool:: = step.::Number of Samples in Pool:: + 1
Sets the value of the Bulk Pool Volume (ul) and PhiX Volume (ul) fields, based on the selected Flowcell Type. The following part of the automation is found in the Calculate Volumes Script field:
step.::PhiX Volume (ul):: = !step.hasValue(::% PhiX (2.5nM) Spike-In::) ? 0 : step.::% PhiX (2.5nM) Spike-In::;
if (input.::Flowcell Type:: == ::SP::) {
step.::Bulk Pool Volume (ul):: = step.::Number of Flowcells to Sequence:: * 100;
step.::PhiX Volume (ul):: *= 0.6
};
if (input.::Flowcell Type:: == ::S1::) {
step.::Bulk Pool Volume (ul):: = step.::Number of Flowcells to Sequence:: * 100;
step.::PhiX Volume (ul):: *= 0.6
};
if (input.::Flowcell Type:: == ::S2::) {
step.::Bulk Pool Volume (ul):: = step.::Number of Flowcells to Sequence:: * 150;
step.::PhiX Volume (ul):: *= 0.9
};
if (input.::Flowcell Type:: == ::S4::) {
step.::Bulk Pool Volume (ul):: = step.::Number of Flowcells to Sequence:: * 310;
step.::PhiX Volume (ul):: *= 1.9
};
if (step.::PhiX Volume (ul):: == 0) {
step.::PhiX Volume (ul):: = ::::
};
Calculates the Per Sample Volume (ul) to be added to the pool. The following part of the automation is found in the Calculate Volumes Script field:
ℹ To ensure accurate pipetting of each sample in a pool for sequencing, the Per Sample Volume (ul) value must be equal to or higher than the Minimum Per Sample Volume (ul). The default value is set at 5, which can be edited.
Assuming the default Minimum Per Sample Volume (ul) value of 5, for a given batch:
If the smallest Per Sample Volume (ul) value is less than 5, Clarity LIMS automatically assigns a value of 5 to the Adjusted Per Sample Volume (ul) field.
Clarity LIMS then adjusts the Adjusted Per Sample Volume (ul) field value for all other samples in the batch, based on the ratio used to increase the lowest value to 5.
Calculates the Total Sample Volume (ul) field value:
Sets the Volume of Pool to Denature (ul) value and calculates NaOH Volume (ul) and Tris-HCl Volume (ul) values, based on the Flowcell Type:
step.::PhiX Volume (ul):: = !step.hasValue('% PhiX (2.5nM) Spike-In') ? 0 : step.'% PhiX (2.5nM) Spike-In';
if (input.::Flowcell Type:: == ::SP::) {
output.::Volume of Pool to Denature (ul):: = 100;
output.::NaOH Volume (ul):: = 25;
output.::Tris-HCl Volume (ul):: = 25;
}
if (input.::Flowcell Type:: == ::S1::) {
output.::Volume of Pool to Denature (ul):: = 100;
output.::NaOH Volume (ul):: = 25;
output.::Tris-HCl Volume (ul):: = 25;
}
if (input.::Flowcell Type:: == ::S2::) {
output.::Volume of Pool to Denature (ul):: = 150;
output.::NaOH Volume (ul):: = 37;
output.::Tris-HCl Volume (ul):: = 38;
}
if (input.::Flowcell Type:: == ::S4::) {
output.::Volume of Pool to Denature (ul):: = 310;
output.::NaOH Volume (ul):: = 77;
output.::Tris-HCl Volume (ul):: = 78;
}
Uses the NovaSeq_Standard_Bulk_Pool1.csv, NovaSeq_Standard_Bulk_Pool2.csv, and NovaSeq_Standard_Bulk_Pool3.csv template files to generate a single CSV file containing information about the pool and the samples it contains. The generated file is available for download on the Step Setup screen of the following step: Dilute and Denature (NovaSeq 6000 v2.3).
Resets the Total Sample Volume (ul) and Number of Samples in Pool field values so that the automation is idempotent:
step.'Number of Samples in Pool' = step.'Number of Samples in Pool' - 1;
step.'Total Sample Volume (ul)' = step.'Total Sample Volume (ul)' - input.'Adjusted Per Sample Volume (ul)'
Set Next Step Automation
Automatically triggered on exit of the Record Details screen, the following automation sets the next step for samples to ADVANCE, advancing them to the Dilute and Denature (NovaSeq 6000 v2.3) step in the protocol:
nextStep = ::ADVANCE::

Protocol 3: NovaSeq Xp (NovaSeq 6000 v2.3)
Samples are routed to this protocol if the Loading Workflow Type value is set to NovaSeq Xp.
Samples are pooled and added to lanes on the NovaSeq flow cell type selected in the Define Run Format (NovaSeq 6000 v2.3) step.
At the end of the protocol, a routing script sends the flow cell to the AUTOMATED - NovaSeq Run (NovaSeq 6000 v2.3) protocol.
This protocol contains three steps:
Step 1: Make Bulk Pool for NovaSeq Xp (NovaSeq 6000 v2.3)
Automatically triggered when the Calculate Volumes button on the Record Details screen is selected, this automation:
Calculates the number of samples in the pool:
step.::Number of Samples in Pool:: = step.::Number of Samples in Pool:: + 1
Sets the value of the Bulk Pool Volume (ul) and PhiX Volume (ul) field, based on the selected Flowcell Type:
step.::PhiX Volume (ul):: = !step.hasValue(::% PhiX (0.25nM) Spike-In::) ? 0 : step.::% PhiX (0.25nM) Spike-In::;
if (input.::Flowcell Type:: == ::SP::) {
step.::Bulk Pool Volume (ul):: = step.'Number of Lanes to Sequence' * 18;
step.::PhiX Volume (ul):: *= 0.7;
}
if (input.::Flowcell Type:: == ::S1::) {
step.::Bulk Pool Volume (ul):: = step.'Number of Lanes to Sequence' * 18;
step.::PhiX Volume (ul):: *= 0.7;
}
if (input.::Flowcell Type:: == ::S2::) {
step.::Bulk Pool Volume (ul):: = step.'Number of Lanes to Sequence' * 22;
step.::PhiX Volume (ul):: *= 0.8;
}
if (input.::Flowcell Type:: == ::S4::) {
step.::Bulk Pool Volume (ul):: = step.'Number of Lanes to Sequence' * 30;
step.::PhiX Volume (ul):: *= 1.1;
}
if (step.::PhiX Volume (ul):: == 0) {
step.::PhiX Volume (ul):: = '';
}
Calculates the Per Sample Volume (ul) to be added to the pool:
input.::Per Sample Volume (ul)::= (((input.::Final Loading Concentration (pM)::* 5/ 1000) / input.::Normalized Molarity (nM)::) * step.::Bulk Pool Volume (ul)::) / step.::Number of Samples in Pool::
ℹ To ensure accurate pipetting of each sample in a pool for sequencing, the Per Sample Volume (ul) value must be equal to or higher than the Minimum Per Sample Volume (ul). The default value set at 5 and can be edited.
Assuming the default Minimum Per Sample Volume (ul) value of 5, for a given batch:
If the smallest Per Sample Volume (ul) value is less than 5, Clarity LIMS automatically assigns a value of 5 to the sample's Adjusted Per Sample Volume (ul) field.
Clarity LIMS then adjusts the Adjusted Per Sample Volume (ul) field value for all other samples in the batch, based on the ratio used to increase the lowest value to 5.
Calculates the Total Sample Volume (ul) field value:
Uses the NovaSeq_Xp_Bulk_Pool.csv and NovaSeq_Xp_Bulk_Pool2.csv template files to generate a single CSV file containing information about the bulk pool and the samples it contains. The generated file is available for download on the Step Setup screen of the following step—Dilute, Denature & ExAmp (NovaSeq 6000 v2.3).
Resets the Total Sample Volume (ul) and Number of Samples in Pool field values so that the automation is idempotent:
step.'Number of Samples in Pool' = step.'Number of Samples in Pool' - 1;
step.'Total Sample Volume (ul)' = step.'Total Sample Volume (ul)' - input.'Adjusted Per Sample Volume (ul)'
Set Next Step Automation
Automatically triggered on exit of the Record Details screen, this automation does the following actions:
Copies the Flowcell Type values from the step inputs to the step outputs.
Sets the next step for samples to ADVANCE, advancing them to the next step in the protocol:
In this step, pooled samples are denatured and diluted by the addition of DPX, NaOH, Tris-HCl, and RSB. Manually create working pools based on the number of lanes you want to sequence. The step input is Bulk pool and the step output is Working pool. Working pool is a variable number for how many working pools need to be created per bulk pool.
These automations are described in the order in which they are triggered at run time.
Validate Inputs Flowcell Type Automation
Automatically triggered at the beginning of the step, this automation invokes the validate_flowcell_for_input_pools script. This script does the following actions:
Checks the inputs to the step and validates that the Flowcell Type field has been set to a valid value (SP, S1, S2, or S4). The automation also checks that all inputs have the same value.
Validates that the number of outputs matches the number of lanes on the selected flow cell type. If validation fails, an error message state that the number of working pools does not match the number of lanes available on the flow cell.
Uses the NovaSeq_Xp_Working_Pool.csv and NovaSeq_Xp_Working_Pool2.csv template files to generate a single CSV file containing information about the DPX volume and the volume of BP Aliquot, Mastermix, NaOH, and Tris-HCI to add per working pool. The generated file is available for download on the Step Setup screen of the following step—Load to Flowcell (NovaSeq 6000 v2.3).
Set Next Step Automation
Automatically triggered on exit of the Record Details screen, this automation:
Copies the Flowcell Type values from the step inputs to the step outputs.
Sets the next step for samples to ADVANCE, advancing them to the next step in the protocol:
The following table provides field configuration details for the fields defined on Dilute, Denature & ExAmp (NovaSeq 6000 v2.3) step. These field values are set by a script and are not editable while running the step.

Step 3: Load to Flowcell (NovaSeq 6000 v2.3)
In this step, scan the flow cell barcode into Clarity LIMS, then manually place the working pools into the lanes of the flow cell that is used in the NovaSeq run. The step input is Working pool and the step output is Flow cell (output containers: S1 and S2 with 2 lanes, and S4 with 4 lanes).
These automations are described in the order in which they are triggered at run time.
Validate Inputs and Selected Container Automation
Automatically triggered at the beginning of the step, this automation invokes the validate_flowcell_for_input_pools and validateSelectedContainer scripts. These scripts validate the step inputs and the container selected, as follows.
Check that the Flowcell Type field has been set to a valid value (S1, S2, S4, or SP) and that all inputs have the same value.
Check that the number of outputs matches the number of lanes on the selected flow cell type. If validation fails, an error message states that the number of working pools does not match the number of lanes available on the flow cell.
The following defines the number of samples allowed for different flow cell types:
SP: 2 working pools
S1: 2 working pools
S2: 2 working pools
S4: 4 working pools
Check that the container type selected on entry to the Placement screen matches the value in the Flowcell Type field. If validation fails, an error message displays.
Validate Flowcell Barcode Automation
Automatically triggered on exit of the Placement screen, this automation validates the flow cell barcode scanned into Clarity LIMS, using the following logic:
if (input.::Flowcell Type:: == ::SP:: && !output.container.name.matches(::[A-Z0-9]{5}DR[A-Z0-9]{2}::)) {
fail(::Invalid Flowcell Barcode. Please verify and try again.::)

};
Generate Sample Sheet & Run Recipe Automation
Automatically triggered when a button on the Record Details screen is selected, this automation:
Copies the Flowcell Type from the step input to the Run Mode field (hidden):
step.::Run Mode:: = input.::Flowcell Type::
Validates the parameters entered on the Record Details screen:

Protocol 4: AUTOMATED - NovaSeq Run (NovaSeq 6000 v2.3)
This final protocol contains one fully automated step, AUTOMATED - NovaSeq Run (NovaSeq 6000 v2.3).
Step 1: AUTOMATED - NovaSeq Run (NovaSeq 6000 v2.3)
Step input: Library tube from the NovaSeq Standard protocol or flow cell from the NovaSeq Xp protocol.
Step output: Result file and measurement.
Do not add samples to the Ice Bucket or start the step manually. This is a fully automated step. The sequencing service may not update samples correctly if they have been manually started.
In this step, pooled samples are sequenced on the NovaSeq instrument. The run data network folder is monitored by the sequencing service and automation worker to determine when the sequencing run begins and ends.
When a run is initiated on the NovaSeq instrument, the NovaSeq Control Software (NVCS) looks for the sample sheet and run recipe (*.json file) on the shared network drive.
The NVCS copies the sample sheet to the run directory.
The NVCS uses the run recipe to start the sequencing run.
When the run starts:
The instrument software creates a new run folder (named <libraryID>) on the shared network drive and copies the following files into that folder:
RunParameters.xml
RunInfo.xml
LIMS/<libraryID>.json file (run recipe)
The Real-Time Analysis v3 (RTA3) software creates the InterOp folder.
The sequencing service detects the presence of the RunParameters, RunInfo, and JSON files and starts the AUTOMATED- NovaSeq Run (NovaSeq 6000 v2.3) step in Clarity LIMS.
As the run progresses, the InterOp data files are filled in.
At the end of the run, the NovaSeq:
Copies the run data files to the InterOp folder.
Creates the CopyComplete.txt file in the run folder. This step indicates to the sequencing service that the run has completed and the data files are ready.
The sequencing service triggers the Read InterOp Metrics automation. This automation reads the files, records the parsed metrics into Clarity LIMS, and finally completes the step in Clarity LIMS.
Parse Run Parameters and Generate Link to Run Folder Automation
Automatically triggered on entry to the Record Details screen, this automation does the following actions:
Parses the RunParameters.xml file attached on the Step Setup screen.
Populates the master and global step fields with extracted values.
If there is an instrument in Clarity LIMS that matches the instrument name in the file (InstrumentName field), the script associates this instrument with the run.
Generates and attaches a link to the run folder using the run output folder parsed from RunParameters.xml.
The following rules and constraints are present:
If there is no InstrumentName value in the file, the script continues, but it logs a warning.
If there is an InstrumentName value in the file and multiple instruments with the same name exist in Clarity LIMS, the script fails and logs an error.
If the RunParameters.xml file is not attached to the step during step setup, the script fails.
Every RunParameters.xml field that has an equivalent step UDF/custom field in Clarity LIMS is required — except for InstrumentName. If a field is not present in the RunParameters.xml file, Clarity LIMS logs an error to this effect.
Read InterOp Metrics Automation
Automatically triggered when the sequencing service detects the CopyComplete.txt file has been created, this automation parses the InterOp data generated by the run.
Read summary metrics are recorded on the library pool. These values are aggregated across all lanes. Some values — for example Yield PF (Gb) — are summed, while others are averaged.
Per lane metrics are recorded on the measurement outputs.
The read_interop_metrics script loads data from the InterOp files and records summary metrics into derived sample UDFs/custom fields in Clarity LIMS. If any field is not configured or cannot be written to, the script fails.
Set Next Steps Automation
Automatically triggered on exit of the Record Details screen, the following automation sets the next step to ADVANCE and the samples complete the protocol:
nextStep = ::ADVANCE::
Update Lane Number Automation
Automatically triggered on exit of the Step Setup screen, this automation updates the lane number so that Read InterOp Metrics automation script can populate lane metric to the correct lane.
⚠ Do not disable Update Lane Number automation as it causes run metric parsing to work improperly.
Master Step Fields
The fields defined on the AUTOMATED - NovaSeq Run (NovaSeq 6000 v2.3) step are listed in the Clarity LIMS Configuration area (Custom Fields > Master Step Fields tab).
The following table shows how the parsed RunParameters.xml fields map to step fields configured on the AUTOMATED - NovaSeq Run (NovaSeq 6000 v2.3) step in Clarity LIMS.

Enter the network output folder location.
Select Save.
For more information, refer to the NovaSeq 6000 Sequencing System Guide at support.illumina.com.
Routing Script Requirements
The requirements for the routing script functionality are as follows.
On the steps that use the routing script — Define Run Format (NovaSeq 6000 v2.3) and Dilute and Denature (NovaSeq 6000 v2.3) — the Next Step for all samples must be set to Remove from workflow. This value is set by a script. Do not change this value in the Assign Next Steps screen.
In the protocol configuration screen, the following setting is required and must not be changed.
In the Next Steps section for the last step in the protocol, the method of assigning the next step must be set to Automatic.
Sample Sheet and Run Recipe File Generation
Sample sheet and run recipe file generation occurs on the step before the run—Dilute and Denature (NovaSeq 6000 v2.3) in the NovaSeq Standard protocol or Load to Flowcell (NovaSeq 6000 v2.3) in the NovaSeq Xp protocol. This step is where samples are placed on the library tube or flow cell that is loaded in the NovaSeq instrument.
In the default configuration, the Generate Sample Sheet & Run Recipe automation generates the following:
One CSV format sample sheet file for use bcl2fastq v2.20 downstream analysis
One JSON format run recipe file
The Prepare Files for NovaSeq automation places the generated files on the NAS where the instrument uses them to start the run.
How It Works
The Prepare Files for NovaSeq automation command line invokes the copy_attachments_to_network_folder script in novaseq-remote-extensions.jar. The script can be used on a remote AI node/automation worker, in case the Clarity LIMS server does not have direct access to the NAS.
The output folder for the run recipe file is found in the novaseq.runSetupFolder property.
The output folder for the sample sheet is determined by using the novaseq.sampleSheetPathPrefixReplace.<suffix> property (not a comma-separated list).
Sample Sheet Contents
The contents of the sample sheet are controlled by the following fields configured on the Dilute and Denature (NovaSeq 6000 v2.3) and Load to Flowcell (NovaSeq 6000 v2.3) steps:
Sample sheet generation script parameters and usage
Sample sheet data and configuration options
Enabling unique FASTQ file names per sequencing run
Run Recipe Contents
The contents of the run recipe are controlled by the following fields. These fields are configured on the Dilute and Denature (NovaSeq 6000 v2.3) and Load to Flowcell (NovaSeq 6000 v2.3) steps.

NovaSeq Xp workflow — Library tube barcode is derived from the Library Tube Barcode field in the Load To Flowcell (NovaSeq 6000 v2.3) step.
Flowcell Barcode (flowcell_ID in JSON file)
NovaSeq Standard workflow — Library tube barcode is not output to JSON recipe file.
NovaSeq Xp workflow — Flow cell barcode is derived from the container name entered or scanned on the Placement screen.
Rehyb — preset to False.
Output Folder (output_folder in JSON file) — Derived from the system property novaseq.seqservice.netPathPrefixSearch.
Attachment — Derived from the system property novaseq.sampleSheetPathPrefixSearch with the name of the sample sheet added to the end of the path.
Use BaseSpace (use_basespace in JSON file) — Set to False if the BaseSpace Sequence Hub Configuration step field value is Not Used, and true otherwise.
Rules and Constraints
The sample sheet and run recipe files are mandatory inputs for the AUTOMATED - NovaSeq Run (NovaSeq 6000 v2.3) step. For the automated run to start successfully, select the Generate Sample Sheet & Run Recipe button to generate these files.
The output folders must exist on the system where the script runs (can be a remote AI node/automation worker).
The output folders must be writable by the glsai user.
Container Types
The integration supports the following container types:
Library tube with barcode provided in the following format:
[A-Z]{2}[0-9]{7}-[A-Z]{3}
Example — NV1234567-LIB
Flow cell with barcode provided in one of the following formats:
For SP and S1 — [A-Z0-9]{5}DR[A-Z0-9]{2}
For S2 — [A-Z0-9]{5}DM[A-Z0-9]{2}
For S4 — [A-Z0-9]{5}DS[A-Z0-9]{2}
Example S2 flow cell barcode — H1234DMXX
Rules and Constraints
The workflow configuration contains several validation checks. To make sure that the calculations work properly, it is important that you do not disable any of this validation logic. The validation checks the following information:
Which samples, and how many, can enter each step together.
Which samples, and how many, can be pooled together.
Reagent labels (indexes) must be unique.
The library tube ID must be unique. There should not be multiple library tube containers in the system with the same name.
Only controls are permitted as unindexed samples. All other unindexed samples and pools are not permitted.
Sample sheet generation script parameters and usage
Sample sheet data and configuration options
Enabling unique FASTQ file names per sequencing run
Do not manually start the AUTOMATED - NovaSeq Run (NovaSeq 6000 v2.3) step. This step is fully automated. If the samples have been manually started, the sequencing service may not update them correctly.
The output folder must be readable by the Clarity LIMS glsjboss account on the server.
