I get the following error on running the following command on catfishq 1.1.15
catfishq -r flowcell_xyz/ --log DEBUG > catf.fastq

Searching flowcell_xyz/ for FASTQ files
Found 622 files
Traceback (most recent call last):

Hi and thanks for the bug report.

Could I ask you what python version you are running catfishq with?

Thanks,
