Very nice!

Is it possible that you have an empty line in the sample sheet?

@mirpedrol tests were finished. But I assume that more of this will become invalid/irrelevant with the move to components

Depending on whether Rx refers to biological or technical replicates, your samplesheet would look something like ``` sample,fastq_1,fastq_2,replicate 12_B9,12_B9_KOL4052A19_S2_L001_R1_001.fastq.gz,12_B9_KOL4052A19_S2_L002_R1_001.fastq.gz,1 12_B9,12_B9_KOL4052A19_S2_L001_R2_001.fastq.gz,12_B9_KOL4052A19_S2_L002_R2_001.fastq.gz,2 12_B9,12_B9_KOL4052A19_S2_L001_R3_001.fastq.gz,12_B9_KOL4052A19_S2_L002_R3_001.fastq.gz,3 13_b10,13_B10_KOL4052A20_S4_L001_R1_001.fastq.gz,13_B10_KOL4052A20_S4_L002_R1_001.fastq.gz,1 13_b10,13_B10_KOL4052A20_S4_L001_R2_001.fastq.gz,13_B10_KOL4052A20_S4_L002_R2_001.fastq.gz,2 13_b10,13_B10_KOL4052A20_S4_L001_R3_001.fastq.gz,13_B10_KOL4052A20_S4_L002_R3_001.fastq.gz,3 ``` or ``` sample,fastq_1,fastq_2,replicate 12_B9,12_B9_KOL4052A19_S2_L001_R1_001.fastq.gz,12_B9_KOL4052A19_S2_L002_R1_001.fastq.gz,1 12_B9,12_B9_KOL4052A19_S2_L001_R2_001.fastq.gz,12_B9_KOL4052A19_S2_L002_R2_001.fastq.gz,1...
