User Interaction, Validation and Troubleshooting
This section explains how to validate the installation of the Illumina NovaSeqDx Integration Package v1.2.0.
The validation process involves the following items:
Running samples through the Library Prep Validation workflow.
The workflow contains a single-step protocol that models the library prep required to produce normalized libraries. At the end of the step, the normalized libraries advance to the workflow selected.
Running normalized libraries through the NovaSeqDx v1.2 workflow validates the following items:
Successful routing of samples from the Run Format (NovaSeqDx v1.2) step to the NovaSeqDx Standard (NovaSeqDx v1.2) or NovaSeqDx Xp (NovaSeqDx v1.2) step.
Automated generation of v2 sample sheet. This file automatically uploads to the sequencing system via the Sequencer API.
Automatic validation of run setup information. Information is uploaded to the NovaSeq 6000Dx Operating Software (NVOS) via the Sequencer API and is used to create the run recipe and initiate the run.
Automated tracking of the NovaSeq 6000Dx sequencing run and parsing of run statistics into Clarity LIMS, via the Sequencer API.
The validation steps assume that the NovaSeqDx Integration Package v1.2.0 is installed and you have imported the default Clarity LIMS configuration.
Activate Workflow, Create Project, Add and Assign Samples
The following steps set up Clarity LIMS in preparation for running samples through the Library Prep Validation v2.3.1 and NovaSeqDx v1.2 workflows.
On the Configuration tab, under Workflows, activate both the Library Prep Validation v2.3.1 and NovaSeqDx v1.2 workflows.
On the Projects and Samples screen, create a project and add samples to it.
Assign the samples to the Library Prep Validation workflow.
Library Prep Protocol: Library Prep Validation v2.3.1
This single-step protocol models the library prep required to produce normalized libraries that are ready for the NovaSeqDx v1.2 workflow.
Follow the steps in Library Prep Validation Protocol to run the Library Prep Validation workflow with the following:
Label Group = TruSeq HT Adapters v2 (D7-D5)
Sequencing Instrument = NovaSeqDx
On exit from the step, the Routing Script automation is triggered. This automation assigns samples to the first step of the NovaSeqDx v1.2 workflow, Define Run Format (NovaSeqDx v1.2). This is the only step in Protocol 1: Run Format (NovaSeqDx v1.2).
Protocol 1: Run Format (NovaSeqDx v1.2)
This protocol includes a single step, Define Run Format (NovaSeqDx v1.2). The step allows for the assignment of per sample values for the following fields:
NovaSeqDx Run Mode
Loading Workflow Type
Normalized Molarity
Flowcell Type
Final Loading Concentration (pM)
At the end of the step, samples are routed to the NovaSeqDx Standard or NovaSeqDx Xp protocol. This routing is done according to the selected Loading Workflow Type. The selected NovaSeqDx Run Mode must be compatible with the Loading Workflow Type and Flowcell Type. The following table shows the compatibility for the combinations of each Flowcell Type based on the NovaSeqDx Standard protocol.
NovaSeqDx Standard Protocol Compatibility
Flowcell Type | Run Mode |
SP | RUO |
S1 | RUO |
S2 | RUO, DX |
S4 | RUO, DX |
The following table shows the compatibility for the combinations of each Flowcell Type based on the NovaSeqDx Xp protocol.
NovaSeqDx Xp Protocol Compatibility
Flowcell Type | Run Mode |
SP | RUO |
S1 | RUO |
S2 | RUO |
S4 | RUO |
Step 1: Define Run Format (NovaSeqDx v1.2)
In Lab View, locate the Run Format (NovaSeqDx v1.2) protocol. The samples are queued for the Define Run Format (NovaSeqDx v1.2) step.
Add the samples to the Ice Bucket and select View Ice Bucket.
On the Ice Bucket screen, select Begin Work.
On the Record Details screen in the Sample Details table, populate the following fields (values can vary across samples):
NovaSeqDx Run Mode — Select DX or RUO.
Loading Workflow Type — Select NovaSeq Standard or NovaSeq Xp from the drop-down list.
Flowcell Type — Select SP, S1, S2, or S4.
Final Loading Concentration (pM) — Select from the two preset options: 225 (for PCR-free workflows), 400 (for Nano workflows), or enter a different value.
Normalized Molarity (nM) — These values are copied over from the previous step. If this column is not populated during library prep, enter the values here.
Select Next Steps, which triggers the Set Next Steps automation and the following actions:
Sets the value of the next step (for all samples) to Remove from workflow. The Routing Script automation expects this value and requires it to advance samples to the next step.
Checks that the NovaSeqDx Run Mode value is compatible with the Loading Workflow Type and Flowcell Type. This automation also generates an error message if the Loading Workflow Type or the Flowcell Type are incompatible.
Calculates the Minimum Molarity.
Checks Normalized Molarity value. For samples with no Normalized Molarity value (eg, empty value, not including 0), generates an error message notifying that the field cannot be empty.
Compares each sample Normalized Molarity value with the Minimum Molarity value.
On the Assign Next Steps screen:
In the Sample Details table, the Next Step for all samples is prepopulated with Remove from workflow, regardless of the Loading Workflow Type.
⚠️ Do not change this value. If Next Step is not set to Remove from workflow, the routing script is not routed samples correctly.
For samples whose Normalized Molarity value is lower than the Minimum Molarity value, the Loading Workflow Type is set to Remove from workflow. A message is recorded in the Warning field for the sample.
To proceed, choose one of the following options:
Return to the Record Details screen and adjust the Normalized Molarity value so that it equals or exceeds the Minimum Molarity value. The Loading Workflow Type must be set to NovaSeq Standard or NovaSeq Xp, as applicable.
Complete the protocol without correcting the Normalized Molarity value. In this case, the samples in question are removed from the Clarity LIMS workflow.
Select Finish Step. The Routing Script automation is triggered:
Samples whose Loading Workflow Type is set to Remove from workflow are removed from the Clarity LIMS workflow. (Occurs when the Normalized Molarity value is lower than the Minimum Molarity.)
Samples whose Loading Workflow Type is set to NovaSeq Standard are routed to the Make Bulk Pool for NovaSeqDx Standard (NovaSeqDx v1.2) step. This step is the first step in the NovaSeqDx Standard protocol.
Samples whose Loading Workflow Type is set to NovaSeq Xp are routed to the Make Bulk Pool for NovaSeqDx Xp (NovaSeqDx v1.2) step. This step is the first step in the NovaSeqDx Xp protocol.
Protocol 2: NovaSeqDx Standard (NovaSeqDx v1.2)
In this protocol, samples are pooled and added to the library tube in preparation for the NovaSeq 6000Dx run. The protocol contains two steps:
Make Bulk Pool for NovaSeqDx Standard (NovaSeqDx v1.2)
Dilute and Denature (NovaSeqDx v1.2)
Step 1: Make Bulk Pool for NovaSeqDx Standard (NovaSeqDx v1.2)
In Lab View, locate the NovaSeqDx Standard (NovaSeqDx v1.2) protocol.

Number of Flowcells to Sequence — Used in volume calculations, to make sure that the volumes are sufficient for the number of times the pool is sequenced.
Minimum Per Sample Volume (ul) — Used to calculate how much of each sample is included in the pool. The field is prepopulated with the configured default value 5 µl, but can be edited.
% PhiX (2.5 nM) Spike-In — Used to calculate the volume of PhiX v3 control included in the pool for the given percentage of spike-in. The field is optional and can be edited.
ℹ️ Assuming the default Minimum Per Sample Volume (ul) value of 5, for a given batch:
If the smallest Per Sample Volume (ul) value is < 5, Clarity LIMS automatically assigns a value of 5 to the Adjusted Per Sample Volume (ul) field.
Clarity LIMS changes 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.
In the Sample Details table, select the pool icon to view details on the pool composition.
Select Calculate Volumes to trigger the Calculate Volumes automation. This automation performs calculations based on the selected Flowcell Type, then generates and attaches the Calculation File (CSV) to the step. This file contains volume information about the pool and the individual samples that it contains.
Select Next Steps to trigger the Set Next Step automation. This automation sets the next step for samples to ADVANCE and advances them to the next step in the protocol, Dilute, and Denature (NovaSeqDx v1.2). The automation also copies the NovaSeqDx Run Mode value from the input pool to the output pool.
On the Assign Next Steps screen, the next step for samples is set to the next step in the workflow: Dilute and Denature (NovaSeqDx v1.2).
Select Finish Step.
At the end of this step, the pool of samples automatically advances to the Dilute and Denature (NovaSeqDx v1.2) step.
Step 2: Dilute and Denature (NovaSeqDx v1.2)
In Lab View, locate the NovaSeqDx Standard (NovaSeqDx v1.2) protocol. The pool of samples queued for the Dilute and Denature (NovaSeqDx v1.2) step are listed.

At this point in the workflow, the user interaction ends. The flow cell is queued for the AUTOMATED - NovaSeqDx Run (NovaSeqDx v1.2) step.
Proceed to AUTOMATED - NovaSeqDx Run (NovaSeqDx v1.2).
⚠️ Do not add samples to the Ice Bucket or start the AUTOMATED - NovaSeqDx Run (NovaSeqDx v1.2) step. The integration adds samples automatically.
Protocol 4: AUTOMATED - NovaSeqDx Run (NovaSeqDx v1.2)
This protocol contains a single fully automated step: AUTOMATED - NovaSeqDx Run (NovaSeqDx v1.2).
The integration starts the step automatically and data from the run is parsed back into Clarity LIMS. User interaction is not required, but you can review the stages of the step in Clarity LIMS (refer to Review Run Data).
Automations
The NovaSeqDx Run (NovaSeqDx v1.2) step contains two automations:
Set Next Steps — This automation is disabled (Set to Not Used). By default, the Sequencer API is used to set the next step for output samples.
The Illumina Preset Protocols (IPP) Package include a Set Next Steps automation configured on the AUTOMATED - NovaSeqDx Run (NovaSeqDx v1.2) step. You can use this automation to override the default next step behavior. For more information, refer to NovaSeq 6000Dx Integration v1.2.0 Configuration.
Update Lane Number — This automation is triggered automatically upon entry to the Record Details screen. To make sure that the Lane Number displays correctly, do not disable or modify this automation.
Review Run Data
Read summary metrics are recorded for the library pool. After the run is complete, open the step and review these metrics displayed on the Next Steps screen in the Step Data section and the Sample Details table.
How the Integration Works
The following steps summarize how the Sequencer API integration works. For details on sample sheet generation and the sequence of events involved in the NovaSeq run, refer to NovaSeq 6000Dx Integration v1.2.0 Configuration.
When setting up a run on the NovaSeq 6000Dx instrument, NVOS sends a request for the run recipe.
The Sequencer API validates that samples and containers are correctly queued for the AUTOMATED - NovaSeqDx Run (NovaSeqDx v1.2) step.
Clarity LIMS sends a JSON response to NVOS. The response includes the run recipe information and a link to download the sample sheet (used with analysis software such as bcl2fastq2).
When the run starts, NVOS sends a RunStarted run status request. The Sequencer API then does the following:
Validates reagent kit information in the RunStarted request:
Verifies that the reagent kit exists. If the reagent kit does not exist, the Sequencer API creates the kit and enables on the master step.
Verifies that the reagent kit is activated. If the reagent kit is not active, the Sequencer API activates it.
Initiates the step for the queued samples. The step produces one output file placeholder per lane of the flow cell in use, based on the flow cell type.
Records all relevant information from the RunStarted request on the step (such as reagent lots and step fields).
At the end of the run, NVOS sends one of the following run status requests:
RunCompletedSuccessfully
RunEndedByUSer
RunErroredOut
The Sequencer API updates the step with any new information, which includes only the status and cycle/read information.
After primary analysis completes, NVOS sends a request containing the parsed run metrics. NVOS sends a request only when the run completes successfully. However, the API does not make this assumption and accepts the request regardless of status. The Sequencer API then does the following:
Records the metrics into the fields on file placeholder outputs in Clarity LIMS.
Completes the step in Clarity LIMS if the status is RunCompletedSuccessfully. For all other status options, the step remains in progress. This action is the default autocomplete step behavior. For more information, refer to NovaSeq 6000Dx Integration v1.2.0 Configuration.
ℹ️ NovaSeq 6000Dx Integration v1.2.0 Configuration provides detailed information on how the following components work with the Sequencer API integration:
Sample sheet generation and contents
NovaSeq 6000Dx run
User authentication and login
Run recipe contents
Troubleshooting
If an automation trigger does not appear to run its corresponding scripts, refer to the following sections in the Clarity LIMS API documentation:
Troubleshooting Automated Worker in the Clarity LIMS (Clarity & LabLink Reference Guide) documentation.
Troubleshooting Automation in the Clarity LIMS (API & Database) documentation.
If an error occurs that does not provide direction on how to proceed, (e.g., the error is related to the AUTOMATED - NovaSeqDx Run (NovaSeqDx v1.2) step) review the log file information. For more details, refer to Logging.
If the automated run step starts, but does not complete, do as follows.
Use one of the following methods to open the in progress step in Clarity LIMS:
Log in to the default user account.
In Lab View, find the step in the Recent Activities pane.
Search for the step in Clarity LIMS. You can use the Library Tube or Flowcell barcode as the search term. The steps depend on whether the search is a NovaSeqDx Standard or NovaSeqDx Xp run.
On the Record Details screen, the Sequencing Log multiline text field contains logging information.
If unable to reach the Record Details screen, or if the Sequencing Log field does not contain enough information to resolve the issue, review the sequencer-api.log file. For details, refer to Logging.
Contact the Clarity LIMS support team. Provide the relevant information from the troubleshooting steps already performed.
Logging
In addition to updating the Sequencing Log multiline text field on the AUTOMATED - NovaSeqDx Run (NovaSeqDx v1.2) step, the Sequencer API writes a detailed log file to
Log messages include the Library Tube ID and Flow Cell ID whenever the messages are related to a sequencing run-related request. In the Clarity LIMS workflows, these IDs are recorded as container names.
Some log messages are not directly related to a sequencing run request, such as downloading the sample sheet. In this case, the file LIMS ID and file name are included in log messages. The sample sheet downloaded by the sequencing system has a name that includes the sequencing container ID (Library Tube for Standard or Flowcell for Xp). The relevant container name search finds most of the log messages for this request. However, the LIMS ID of the file must be known in order to retrieve all messages related to the file download. The LIMS ID is found in the Clarity LIMS API and, for sample sheets used in a run, in the recipe response (which can also be found in the log file).
Example lines from the log file:
