The samplesheet has to be a comma-separated file with a minimum set of columns (which will vary depending of the pipeline you are interested to run), and a header row.

Column names has to be specified in a header row as shown in the samplesheet example below:

For the nf-core/rnaseq pipeline, the samplesheet has to be a comma-separated file with the following 4 columns:
...
Column names has to be specified in a header row as shown in the samplesheet example below:
...
sample,fastq_1,fastq_2,strandedness
CONTROL_REP1,AEG588A1_S1_L002_R1_001.fastq.gz,AEG588A1_S1_L002_R2_001.fastq.gz,auto
CONTROL_REP1,AEG588A1_S1_L003_R1_001.fastq.gz,AEG588A1_S1_L003_R2_001.fastq.gz,auto
CONTROL_REP1,AEG588A1_S1_L004_R1_001.fastq.gz,AEG588A1_S1_L004_R2_001.fastq.gz,auto

Please note that in this example, the same sample (CONTROL_REP1) was sequenced across 3 lanes. The nf-core/sarek pipeline will concatenate the raw reads before performing any downstream analysis.
