Do not merge .fastq's per sample if there is only one .fastq
Currently, all .fastqs are joined per sample as seen here:
However, this also happens in case there is only one .fastq per sample (thus already the sample .fastq):
data:
WT-1:
cDNA_reads: ['A4_L003_R2.fastq.gz']
barcode_reads: ['A4_L003_R1.fastq.gz']
WT-2:
cDNA_reads: ['B4_L003_R2.fastq.gz']
barcode_reads: ['B4_L003_R1.fastq.gz']
It takes a long time to copy the files, so it would be great if the pipeline would only would be great if the pipeline would only copy them in case there are >1 files.
