This workflow splits a multi-sample VCF file into individual single-sample VCF files. This is achieved by first\nextracting all the samples from the provided multi-sample VCF file. The extracted samples are then broken up into\n"chunks" based on the specified chunk size. A new sample list is generated per chunk. Finally, this new "chunked"\nsample list is used to extract the corresponding samples from the original multi-sample VCF file, creating new\nsingle-sample VCF files. These files (and corresponding index files, if requested) are then copied to the specified\noutput location.
\n| Parameter Name | Description | Type | Required | Default |\n|----------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------|---------|----------|-----------------------------------------------------------------------------|\n| multiSampleVcf | The GCP path to the multi-sample VCF. | File | Yes | N/A |\n| outputLocation | Where the single-sample VCFs (and indices, if requested) should be written to.
