DRAGEN TSO 500 ctDNA Analysis Software has optional and required fields that are required in addition to general sample sheet requirements. Follow the steps below to create a valid samplesheet.
TSO 500L Data Section header changes depending on the deployment:
Standalone DRAGEN Server and ICA with Manual Launch: TSO500L_Data
ICA with Auto-launch: Cloud_TSO500L_Data
Sample_ID
Required
The unique ID to identify a sample. The sample ID is included in the output file names. Sample IDs are not case sensitive. Sample IDs must have the following characteristics:
- Unique for the run.
- 1–40 characters.
- No spaces.
- Alphanumeric characters with underscores and dashes. If you use an underscore or dash, enter an alphanumeric character before and after the underscore or dash. eg, Sample1-T5B1_022515.
- Cannot be called all, default, none, unknown, undetermined, stats, or reports.
- Must match a Sample_ID listed in the BCL Convert Data section.
- Each sample must have a unique combination of Lane (if applicable), sample ID, and index ID or the analysis will fail.
Sample_Type
Required
Enter DNA
Sample_Description
Not Required
Sample description must meet the following requirements: - 1–50 characters. - Alphanumeric characters with underscores, dashes and spaces. If you enter a underscore, dash, or space, enter an alphanumeric character before and after. eg, Liquid-Sample_213.
To ensure a successful analysis, follow these guidelines:
Avoid any blank lines at the end of the sample sheet; these can cause the analysis to fail.
When running local analysis using the command line save the sample sheet in the sequencing run folder with the default name SampleSheet.csv, or choose a different name and specify the path in the command-line options.
Refer to the following requirements to create sample sheets for running the analysis on ICA with Auto-launch. For sample sheet requirements common between deployments see Standard Sample Sheet Requirements. Samples sheets can be created using BaseSpace Run Planning Tool or manually by downloading and editing a sample sheet template
To auto-launch analysis from the sequencer run folder, ensure the StartsFromFastq and SampleSheetRequested fields are set to FALSE. To auto-launch analysis from FASTQs after BCL Convert auto-launch, StartsFromFastq and SampleSheet Requested fields must be set to TRUE

Sample Sheet templates for TSO 500 ctDNA standalone DRAGEN server and ICA manual launch analysis can be found in the table below. For auto-launch compatible sample sheets, use BaseSpace Run Planner.
DRAGEN TSO 500 ctDNA analysis software is compatible with several instruments and assay workflows, each of which have implications for the sample sheet.
Sample sheet templates contain all required fields, including index sequences in the proper orientation for all indexes from a given library prep kit. The templates are provided as a starting point for creating a sample sheet manually when launching analysis on a standalone DRAGEN server or on ICA using manual launch.
For interactive run planning or to create a sample sheet for ICA Autolaunch, use to create valid sample sheets for either local or cloud analysis. To set up a run in BaseSpace run planner, refer to .
Users can visit the section to learn additional details on required fields and values as they fill-in their sample information. Use the lookup table below to select and download the sample sheet template that matches your instrument, assay, and workflow configuration:
A sample sheet is required for each analysis with DRAGEN TruSight Oncology 500 ctDNA Analysis Software. A sample sheet is a comma-separated value (*.csv) file format used by Illumina instruments, platforms, and analysis pipelines to store settings and data for sequencing and analysis. The DRAGEN TruSight Oncology 500 ctDNA Analysis Software is compatible with the sample sheet v2. For general information on the sample sheet v2, refer to .
The sample sheet includes a list of samples and their index sequences, along with additional information required to run DRAGEN TruSight Oncology 500 ctDNA Analysis Software. For example, the library prep kit used for analysis will need to be listed in the sample sheet. Appropriate index adapter sequences are determined by the assay used to perform analysis.
When running analysis on a standalone DRAGEN server or on ICA, a valid sample sheet can be created by:
BaseSpace Run Planner (preferred), see for details
Downloading and modifying a sample sheet template following the requirements, see for details
When running analysis using a NovaSeq 6000Dx Analysis Application, a valid sample sheet can be created by:
Using the user interface of the DRAGEN TruSight Oncology 500 ctDNA Analysis Application, see for details
Downloading and modifying a sample sheet template following the requirements (see for details), then importing it to Illumina Run Manager.
The run set up section of this guide includes specific instructions to plan a run and set up a valid sample sheet for each deployment of DRAGEN TruSight Oncology 500 ctDNA Analysis Software.
Alternately, select Import Samples to upload sample information. Refer to for sample sheet requirements.
The BaseSpace Sequence Hub Run Planning tool is available, and is used to generate a valid sample sheet in v2 format for use on a TSO 500 ctDNA supported sequencer for both ICA and Standalone DRAGEN Server analysis options. Filling out the form on the user interface will produce a exportable sample sheet with the required fields filled in. Refer to ICA Auto-launch Sample Sheet Requirements for descriptions of fields that appear in ICA sample sheets.
The sections below represent each step in the BaseSpace Run Planning tool.
Note that NovaSeq X Series has a different run set up configuration screen than other instrument platforms. TSO 500 ctDNA does not support multi analysis, and in order to run TSO 500 ctDNA on NovaSeq X Series, enter the appropriate Read 1, Read 2, Index 1 and Index 2 described in the instructions below.

Once all details are captured and pass validation, the user can review the details on the Run Review screen. From here they can choose to edit details in previous screens or export the sample sheet. Once completed, press the Cancel button to finish run planning.
Note: once leaving this screen, the run and sample sheet will not be accessible.
For NovaSeqX Plus users, the run can be saved as a draft or as a planned run (via “Save as Draft” and “Save as Planned” buttons respectively). Either selection will save the run to the Planned Runs screen on BaseSpace. There is no option to export the sample sheet on this screen.
The Planned Runs screen lists all planned or drafted runs. Users can set drafted runs to planned, export the sample sheet, and edit or delete a run on this screen.
Once the run is saved as Planned, it will appear on the NovaSeq X Series instrument where it can be selected for sequencing.
