Cloud URN Support

We also support URNs for BSSH auto-launch

The urn attribute can be placed either in the Cloud_Settings section under the key <app_name>_Pipeline or the settings section of the application under the key urn. In both circumstances, the urn will be placed in the cloud settings section of the samplesheet under <app_name_Pipeline>.

When using the Cloud_Settings and Cloud_Data section, one should place the library_prep_kit_name and index_adapter_kit_name for each element in bclconvert_data.

One will also need to place the following key, value pairs under the cloud_settings key:

• generated_version: "0.0.0",
• cloud_workflow: "ica_workflow_1"

An example can be seen below:

Testing your outputs

The v2-samplesheet-maker will validate that your parameters are the correct type, the correct name AND within the appropriate range. It will NOT however determine if your settings are appropriate or compatible with a BCLConvert run, i.e it will NOT ensure that your indexes have an appropriate hamming distance.

If you wish to validate your output samplesheet with BCLConvert, you can use the following script -

scripts/build-samplesheet-and-validate-with-bcl-convert.sh <input-json> [docker-image]. This will convert the input json to csv and then run the docker container bclconvert against your samplesheet.

You will need both jq and docker installed for this to work.

Additional Usage

Parsing a SampleSheet CSV to JSON

We also have created a parser between the csv and json, with the following usage syntax

v2-samplesheet-to-json SampleSheet.csv -

Manipulating a samplesheet by parsing through JSON

For this component, you will need some basic knowledge of the jq command line tool.

In this example we are given a standard samplesheet but want to edit the adapters for one of the samples.

Whilst we could do this with grep, sed or awk, it's a little hacky, instead we can

1. Parse the samplesheet to json to stdout
2. Use jq to update the samplesheet
3. Write out the updated samplesheet to csv

# Initialise new index variable
NEW_I7_INDEX="TTTTTTTTTT"
SAMPLE_ID="MySecondSample"

# Convert the SampleSheet to JSON
# Update the index for the sample "MySecondSample" in the bclconvert_data section
# Write out the new samplesheet to csv
v2-samplesheet-to-json SampleSheet.csv - | \
jq --raw-output \
  --arg sample_id "${SAMPLE_ID}" \
  --arg replacement_index "${NEW_I7_INDEX}" \
  '
    .bclconvert_data=( 
      .bclconvert_data |
      map(
        if .sample_id == $sample_id then
          .index = $replacement_index
        else
          .
        end
      )
    )
  ' | \
v2-samplesheet-maker - SampleSheet.updated_index.csv 

Gives us the following samplesheet as an output

[Header]
FileFormatVersion,2
RunName,my-illumina-sequencing-run
RunDescription,A test run
InstrumentPlatform,NovaSeq 6000
InstrumentType,NovaSeq

[Reads]
Read1Cycles,151
Read2Cycles,151
Index1Cycles,10
Index2Cycles,10

[BCLConvert_Settings]
AdapterBehavior,trim
BarcodeMismatchesIndex1,1
BarcodeMismatchesIndex2,1
MinimumAdapterOverlap,2
OverrideCycles,Y151;Y10;Y8N2;Y151
CreateFastqForIndexReads,False
NoLaneSplitting,False
FastqCompressionFormat,gzip

[BCLConvert_Data]
Lane,Sample_ID,index,index2,Sample_Project
1,MyFirstSample,AAAAAAAAAA,CCCCCCCC,SampleProject
1,MySecondSample,TTTTTTTTTT,TTTTTTTT,SampleProject

If we run a diff on our original and updated samplesheet, we can see that the index for "MySecondSample" has been updated.

diff SampleSheet.csv SampleSheet.updated_index.csv

Yields

27c27
< 1,MySecondSample,GGGGGGGGGG,TTTTTTTT,SampleProject
---
> 1,MySecondSample,TTTTTTTTTT,TTTTTTTT,SampleProject
