Configuration

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.

For instructions on user interaction for each step, validating and troubleshooting the Illumina NovaSeq 6000 Integration, refer to NovaSeq 6000 Integration v2.6.0 User Interaction, Validation and Troubleshooting.

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).

For more information on sample accessioning, refer to Sample Accessioning and Upload and Modify Samples in the Getting Started section of the Clarity LIMS (Clarity & LabLink Reference Guide) documentation.

You can assign samples to workflows automatically, using a routing script, or manually—from the Projects & Samples dashboard. Refer to Assign and Process Samples in the Clarity LIMS (Clarity & LabLink Reference Guide) documentation.

Workflows, Protocols, and Steps

The Illumina NovaSeq 6000 Integration Package v2.6.0 includes two workflows:

• NovaSeq Validation Library Prep (NovaSeq 6000 v2.3)
• NovaSeq 6000 v2.3

NovaSeq Validation Library Prep (NovaSeq 6000 v2.3) Workflow

Protocol: NovaSeq Validation Library Prep (NovaSeq 6000 v2.3)

Purpose:

• 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).

Steps:

1. NovaSeq Validation Library Prep (NovaSeq 6000 v2.3)

NovaSeq 6000 v2.3 Workflow

Protocol 1: Run Format (NovaSeq 6000 v2.3)

Purpose:

• 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:

1. 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:

1. Make Bulk Pool for NovaSeq Standard (NovaSeq 6000 v2.3)
2. 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:

1. Make Bulk Pool for NovaSeq Xp (NovaSeq 6000 v2.3)
2. Dilute, Denature & ExAmp (NovaSeq 6000 v2.3)
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.

Steps:

1. AUTOMATED - NovaSeq Run (NovaSeq 6000 v2.3)

Validation Workflow

The NovaSeq Validation Library Prep (NovaSeq 6000 v2.3) workflow allows for validation of the system after installation is complete. For details, refer to NovaSeq 6000 Integration v2.6.0 User Interaction, Validation and Troubleshooting.

Protocol 1: Run Format (NovaSeq 6000 v2.3)

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
• 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:
• 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:

  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:

1. Make Bulk Pool for NovaSeq Standard (NovaSeq 6000 v2.3)
2. 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.
• Only one pool has been created.

Calculate Volumes Automation

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:
• 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:
• 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:

  1. 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.
  2. 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:
• If the Total Sample Volume is less than the Bulk Pool Volume, calculates the RSB Volume (ul) field value:
• Copies the Flowcell Type and Loading Workflow Type values from the step inputs to the step outputs:
• 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:
• 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 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.
