Add header only one time

[jodjo86]

Hi,

Do you think it is possible to add the header only once. The -s argument controls whether to have no header or one header per fastq file.

example command I am using:
parallel faster -ts ::: /path/to/fastq/*.fastq.gz > out.tsv

thank you

Hi,
it is not possible directly. One solution would be to run faster -t example.fastq.gz > out.tsv once to get the header and then in subsequent runs with parallel append to the previous output:
parallel faster -ts ::: /path/to/fastq/*.fastq.gz >> out.tsv

Good idea. Thank you
