Update test data for bcl_demultiplex subworkflow #1240

Closed k1sauce closed 5 months ago

k1sauce commented 5 months ago

Illumina's BCL Convert software generates FASTQ files for sequencing data run directory containing BCL files. The demultiplexing process involves assigning reads to a FASTQ files as specified by the indices (barcodes) in the SampleSheet.csv file. If no reads can be assigned to the barcode, bcl-convert generates an empty FASTQ. The empty FASTQ file has caused error in the bcl_demultiplex subworkflow. The fix should include a test case for empty FASTQs. We can include a sample with indices in the SamleSheet.csv that are not used in the library prep to generate the empty FASTQ file during the test.
