Release Date: June 2024

Document Version: 2

These release notes describe the key changes to software components for the Clarity LIMS NextSeq 1000/2000 On-Prem Integration Package v1.0.0.

Compatibility

Refer to Compatibility under Instruments & Integrations.

New Features

• The new on-premise integration for NextSeq 1000/2000 supports the following functions:

  • Automated generation of a sample sheet for use with the BCL Convert analysis software.

  • Automated tracking of the sequencing run and parsing of run statistics into Clarity LIMS.

  • Automated tracking of the local DRAGEN BCL Convert analysis (BCL Convert v4.2.7 and earlier) and parsing of demultiplexing metrics into Clarity LIMS. The metrics are aggregated for multi-lane flow cells (for example, P3).

Defect Repairs

• None

Known Issues

• Sequencing run error triggered by disk space full on instrument causes RunParameters.xml to be empty and the run event cannot be processed on Clarity LIMS. This error is unlikely to occur as pre-run checks on the instrument check for sufficient disk space before run is started.

Limitations

• Does not support analysis requeue.

Revision History

The documents in this section support the Illumina NextSeq 1000/2000 Integrations. These integrations are compatible with Illumina cloud hosted deployments as well as on-premise integrations without internet connections.

The NextSeq 1000/2000 On-Prem Integration Package v1.0.0 enables run planning through the v2 sample sheet that is generated or imported. The integration also tracks both sequencing run and GenerateFASTQ analysis run events without a connection to BaseSpace Sequence Hub or ICA.

The integration includes:

• The preconfigured NextSeq 1000/2000 On-Prem Sequencing v1.0 workflow that maps to lab protocols, instrument runs, and GenerateFASTQ analysis.

• The following preconfigured steps:

  • Library Pooling and Dilution (NextSeq 1000/2000 On-Prem Sequencing v1.0)

  • Load To Reagent Cartridge (NextSeq 1000/2000 On-Prem Sequencing v1.0)

  • AUTOMATED - Sequencing Run (NextSeq 1000/2000 On-Prem Sequencing v1.0)

  • Demultiplexing (NextSeq 1000/2000 On-Prem Sequencing v1.0)

• Automated generation of the v2 sample sheet using Driver File Generator to set up Local Run Mode sequencing and GenerateFASTQ analysis runs.

• Automated copying of the generated v2 sample sheet to a network drive location so that the instrument can import it.

• Automated tracking of the sequencing run and parsing of run statistics into Clarity LIMS, including:

  • Progress and metrics of sequencing run

  • Sequencing run parameters

  • Reagent lot information

  • Sequencing run data directory location

  • Instrument software version

  • Real-Time Analysis (RTA) version and other run specific information

• Automated tracking of local secondary analysis using DRAGEN (up to BCL Convert only) and parsing of demultiplexing metrics into Clarity LIMS. The local BCL Convert is supported up to v4.2.7.

• [Optional] Preconfigured Library Prep Validation v2.3.3 protocol used for validation purposes only. This workflow contains a single-step protocol that models the library prep required to produce libraries tagged with index sequences that are ready for the NextSeq 1000/2000 On-Prem Sequencing v1.0 workflow. For more information, refer to NextSeq 1000/2000 On-Prem Integration v1.0.0 User Interaction, Validation and Troubleshooting.

This section explains how to validate the installation of the Illumina NextSeq 1000/2000 On-Prem Integration Package v1.0.0.

The validation process involves the following items:

• Running samples through the Library Prep Validation v2.3.3 workflow.

  • The workflow contains a single-step protocol that models the library prep workflow required to produce libraries tagged with index sequences. At the end of the step, these libraries are routed to NextSeq 1000/2000 On-Prem Sequencing v1.0 workflow.

• Running the libraries through the NextSeq 1000/2000 On-Prem Sequencing v1.0 workflow. This process validates the following information:

  • Successful sequential step advancement of samples in the following steps:

    1. Library Pooling and Dilution (NextSeq 1000/2000 On-Prem Sequencing v1.0)

   • Label Group = TruSeq HT Adapters v2 (D7-D5)

   • Sequencing Instrument = NextSeq 1000/2000 On-Prem

   On exit from the step, the Routing Script automation is triggered. This automation assigns samples to the first step of the NextSeq 1000/2000 On-Prem Sequencing v1.0 workflow, which is Library Pooling and Dilution (NextSeq 1000/2000 On-Prem Sequencing v1.0) step.

NextSeq 1000/2000 On-Prem Sequencing v1.0 Protocol

Step 1: Library Pooling and Dilution (NextSeq 1000/2000 On-Prem Sequencing v1.0)

1. In Lab View, locate the NextSeq 1000/2000 On-Prem Sequencing v1.0 protocol. The samples are queued for the Library Pooling and Dilution (NextSeq 1000/2000 On-Prem Sequencing v1.0) step.

2. Add the samples to the Ice Bucket and select View Ice Bucket.

3. On the Ice Bucket screen, select Begin Work.

4. On the Pooling screen, perform the following actions:

   1. Create a pool by dragging samples into the Pool Creator.
   2. Type a name for the pool or accept the default name (Pool #1).

   1. Select Record Details.

      On the Record Details screen, the Reagent Lot Tracking section tracks the Resuspension Buffer (RSB) lot information used in the step.

5. In the Reagent Lot Tracking section, select from the active lots displayed in the drop-down list.

   The Step Details area contains two required fields:

   • Final Loading Concentration (pM) — The value entered in this field is the recommended final loading concentration specified in the Illumina NextSeq 1000/2000 Sequencing System Guide. The value depends on the library type. The default drop-down list contains the values 650, 750, 1000, and 2000. A custom value is acceptable.

   • Final Loading Volume (ul) — The value in this field is the final loading volume of the pool into the reagent cartridge. The field is prepopulated with the configured default value, 24 µl, specified in the Illumina NextSeq 1000/2000 Sequencing System Guide. The value is editable when more volume is necessary.

6. Select Calculate Volumes.

   This selection triggers the Calculate Volumes automation. This automation calculates the volume required for each library to form a pool that has the concentration and volume specified in the step details fields.

   The automation also generates the Calculation File (CSV) and attaches it to the step. This file contains volume information of each of the samples and RSB buffer to add to the pool. Select the file to download it, then open it in Excel.

7. In the Sample Details table, select the pool icon to view details on the pool composition.
8. Select Next Steps.

   This selection triggers the Set Next Step automation, which sets the next step for samples to ADVANCE, advancing them to the next step in the protocol. The next step is Load To Reagent Cartridge (NextSeq 1000/2000 On-Prem Sequencing v1.0).

   On the Assign Next Steps screen, the next step for samples is already set to the next step in the workflow. The next step is Load To Reagent Cartridge (NextSeq 1000/2000 On-Prem Sequencing v1.0).

9. Select Finish Step.

At the end of this step, the pool of samples automatically advances to Load To Reagent Cartridge (NextSeq 1000/2000 On-Prem Sequencing v1.0) step.

Step 2: Load To Reagent Cartridge (NextSeq 1000/2000 On-Prem Sequencing v1.0)

1. In Lab View, locate the NextSeq 1000/2000 On-Prem Sequencing v1.0 protocol.

   The pool of samples is queued for the Load To Reagent Cartridge (NextSeq 1000/2000 On-Prem Sequencing v1.0) step.

   On the Assign Next Steps screen, the next step for samples is set to the next step in the workflow. The next step is AUTOMATED - Sequencing Run (NextSeq 1000/2000 On-Prem Sequencing v1.0).

10. Select Finish Step.

At the end of this step, the pool of samples automatically advances to and is queued for the AUTOMATED - Sequencing Run (NextSeq 1000/2000 On-Prem Sequencing v1.0) step. The sequencing run is ready to be started. For details on how to start the sequencing run for the local run mode, refer to NextSeq 1000/2000 On-Premise Integration v1.0.0 Configuration.

Step 3: AUTOMATED - Sequencing Run (NextSeq 1000/2000 On-Prem Sequencing v1.0)

This step is fully automated.

The integration starts the step automatically and data from the run is parsed back to Clarity LIMS. No user interaction is required. However, you can open and review the various stages of the step in Clarity LIMS. Do not perform any action when reviewing the data.

Read summary metrics are recorded for the library pool in the Step Details section and the Sample Details table.

Values are populated in the following master step fields:

• Run Name

• Current Read

• Flow Cell ID

• Reagent Cartridge Lot Number

• Instrument ID

• Run Status

• Current Cycle

• Flow Cell Lot Number

• Instrument Platform

• Instrument Control Software Version

• Output Folder

• Secondary Analysis Workflow

• Reagent Cartridge ID

• Instrument Type

• RTA Version

• Sequencing Log

The summary metrics (per run level) populate in the following global fields.

• % Bases >=Q30 R1

• % Bases >=Q30 R2

• % Error Rate R1

• % Error Rate R2

• Yield (Gb) R1

• Yield (Gb) R2

• Reads PF R1

• Reads PF R2

• %PF R1

• %PF R2

• % Aligned R1

• % Aligned R2

• % Phasing R1

• % Phasing R2

• % Prephasing R1

• % Prephasing R2

• Intensity Cycle 1 R1

• Intensity Cycle 1 R2

• Cluster Density R1

• Cluster Density R2

At the end of this step, the pool of samples automatically advances to (and queues for) the Demultiplexing (NextSeq 1000/2000 On-Prem Sequencing v1.0) step.

Step 4: Demultiplexing (NextSeq 1000/2000 On-Prem Sequencing v1.0)

This step is semi-automated.

The integration starts the step automatically and demultiplexing data from the GenerateFASTQ secondary analysis is parsed back to Clarity LIMS. Review the data parsed and assign QC, depending on the criteria set, and complete the step.

In the Record Details screen, perform the following actions:

1. Review demultiplexing data.

   • Demultiplexing metrics are recorded for the library pool in the Sample Details table. For multi-lane flow cells (for example, P3), the metrics are aggregated by summing them across all lanes. For example, the # Reads displayed in the Sample Details table for a P3 flow cell (two lanes) is the summed value of the number of reads in Lane 1 and Lane 2 of Demultiplex_Stats.csv.

   • The metric files that are generated by the DRAGEN onboard are stored under the Files section as Run_Metrics.zip.

2. Assign QC flags to the individual samples. There are two ways of doing this step.

   1. Manually assign QC flags through the QC column in Sample Details table.
   2. Automatically assign QC flag by running Assign QC flags automation. This option is for scenarios where a huge number of libraries are involved.

      In the Step Details section, the following step fields are visible. (N is the number of criteria. You can use one or more criteria.)

      • Criteria N - Source Data Field — Select from preset options (for example, # Reads).

      • Criteria N - Operator — Select from preset options (for example, >= (greater than or equal to)).

      • Criteria N - Threshold Value — Enter the desired threshold value.
3. After filling up the criteria fields, select Assign QC flags. This selection triggers the automation script, which loops through each library in the pool and apply QC flag base on the criteria set previously.

   This automation also generates an AssignQC Result file under Files section.
4. Select Next Steps.

   On the Assign Next Steps screen, the Next Step field for all samples is prepopulated with Mark protocol as complete.
5. Select Finish Step.

At this point, the whole NextSeq 1000/2000 On-Prem Integration workflow is fully validated.

Troubleshooting

If an automation trigger does not appear to run its corresponding scripts, refer to Troubleshooting Automation in the Clarity LIMS (API & Database) documentation.

If the AUTOMATED - Sequencing Run (NextSeq 1000/2000 On-Prem Sequencing v1.0) step starts but does not finish, complete the following steps:

1. Log in to Clarity LIMS using the default user account and use one of the following methods to open the step in Clarity LIMS:

   • Method 1: In Lab View, find the step in the Recent Activities pane.

   • Method 2: Search for the step in Clarity LIMS using reagent cartridge barcode as the search term.

2. On the Record Details screen, locate the Sequencing Log field.

   The multiline text field contains logging information.

If you cannot reach the Record Details screen, or if the Sequencing Log field does not contain enough information to resolve the issue, contact the Clarity LIMS support team. Supply the relevant information from the troubleshooting steps already performed.

For instructions on validating and troubleshooting the NextSeq 1000/2000 Integration, refer to NextSeq 1000/2000 On-Prem Integration v1.0.0 User Interaction, Validation and Troubleshooting.

The configuration provided in this integration has been established to support NextSeq 1000/2000 lab processes. Any configuration changes to protocols or workflows (including renaming protocols, steps, and fields) could break the process.

When the Library Prep Validation v2.3.3 workflow is imported, it includes the Illumina Universal Sample Identifier global field. This field is a text field that is reserved for CLPA support and is optional. The value of this field is not required for this integration.

Prerequisites and Assumptions

It is assumed that samples entering the NextSeq 1000/2000 On-Prem Sequencing v1.0 workflow have gone through library preparation and quantification processes. Before they are assigned to the workflow, samples have completed the following actions:

• Samples have been accessioned into Clarity LIMS.

• Samples have been run through QC and library prep.

• Samples have the Molarity (nM) global field set to some value.

  The Calculate Volumes automation in the Library Pooling and Dilution step requires a value in the Molarity (nM) global field.

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.

How the NextSeq 1000/2000 On-Premise Integration Works

The following diagram shows how the integration works between the NextSeq 1000/2000 and Clarity LIMS.

Sample Sheet Generation

On the Load To Reagent Cartridge (NextSeq 1000/2000 On-Prem Sequencing v1.0) step, the run and analysis parameters entered in the Run Details screen are validated using the scripts in this step. This validation occurs when the Validate Run Setup and Create Sample Sheet automation is triggered. If the validation passes, Clarity LIMS generates the sample sheet using the driver file generator. The sample sheet contains all the run and analysis configuration required to start the run on the instrument.

For more information on how to start a local run, refer to instructions for initiating a sequence run in the NextSeq 1000/2000 Product Documentation.

Run Status, Primary Metrics, and Analysis Results Parsing and Recording

After the sequencing run is started on the instrument, the instrument generates the files as the sequencing and analysis run progresses. The integration monitors these files to track the run.

The following table shows the run statuses and how the integration service handles them.

Run Status

The integration immediately starts the Demultiplexing (NextSeq 1000/2000 On-Prem Sequencing v1.0) step after completing the AUTOMATED - Sequencing Run (NextSeq 1000/2000 On-Prem Sequencing v1.0) step. In the Demultiplexing step, the integration does the following actions:

• Searches for the CopyComplete.txt file produced by the instrument as a sign that the analysis is complete.

  • After analysis is completed, the integration downloads the Demultiplex_Stats.csv file that contains the demultiplexing results. Then, the integration zips the run metric files (Adapter_Metrics.csv, Demultiplex_Stats.csv, Index_Hopping_Counts.csv, Quality_Metrics.csv, and Top_Unknown_Barcodes.csv) and attaches the Run_Metrics.zip file to the step. After detecting the Demultiplex_Stats.csv file, the Analysis Status field is updated to Completed. Otherwise, this field is set to Failed to signal that the BCL Convert analysis has failed.

  • The Demultiplex_Stats.csv file is parsed and details are recorded in the Sample Details table for each library in the library pool. For multi-lane flow cells, the demultiplex details (for example, number of reads) are aggregated as a sum.

• Updates the Multiline Sequencing Log field.

The integration does not automatically complete the step. You must assign the QC flag to the individual library before manually completing the step.

Start A Sequencing Run On Instrument

For more information on how to start a local run, refer to instructions for initiating a standard SBS or XLEAP-SBS sequencing run in the NextSeq 1000/2000 Product Documentation.

Enabling Planned Run Generation for Samples Having Duplicate Name with Different Indexes

The library preparation workflow of the samples must be configured to ensure unique derived sample names before routing the samples through the library preparation workflow.

Components Installed

The following sections describe the various components that are installed by default as part of this integration. These components include the following items:

• Reagent categories/label groups

• Reagent kits

• Control types

• Containers

Information on installed workflows, protocols, steps, and automation points is provided in the Workflows, Protocols, and Steps section of NextSeq 1000/2000 On-Prem Integration v1.0.0 User Interacion, Validation and Troubleshooting.

Reagent Categories/Label Groups

• TruSeq HT adapters v2 (D7-D5)

Reagent Kits

• Resuspension Buffer (RSB)

• NextSeq 1000/2000 reagent cartridge

Container Types

• Tube

• 96-well plate

• NextSeq 1000/2000 reagent cartridge

Control Types

• PhiX v3

This integration supports the NextSeq 1000/2000 reagent cartridge with barcode provided in the format [A-Z]{2}[0-9]{7}-[A-Z0-9]{4} (for example, EC1234567-EC03).

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 determine:

  • Which samples, and how many, can enter each step together.

  • Which samples, and how many, can be pooled together.

• The NextSeq 1000/2000 reagent cartridge barcode must be unique. There must not be multiple NextSeq 1000/2000 reagent cartridge containers in the system with the same name.

• Reagent labels (indexes) must be unique.

• One library pool can only contain one library or control with no label (index).

• Do not manually start or complete the AUTOMATED - Sequencing Run (NextSeq 1000/2000 On-Prem Sequencing v1.0) step. This step is a fully automated step, and the integration service does not update samples correctly if they have been manually started.

• Do not manually start the Demultiplexing (NextSeq 1000/2000 On-Prem Sequencing v1.0) step. This step is semi-automated, and the SIS integration service does not update the demultiplexing results correctly if they have been manually started.
