FASTX error - quality score

Hi, I am using the FastX collapser option, with the Q33 option, as my reads were sequenced by illumina and yet I get an error msg: "invalid quality score data..."

the command I ran was fastx_collapser -Q33 -i infile.fq -o outfile.fq

Thanks!

The part of the error message that you did not quote after the "..." probably contains relevant information. Can you fully quote the message and provide a minimal test example ?

I figured it out - the file was corrupted, and a line existed with only quality scores and no sequence data.... Thanks!
