PRINSEQ bug with -no_qual_header

[Emmanuelle Beyne]

Hello,

I have several FASTQ files (from Illumina sequencing) with reads as the following :

@ST-E00181:926:HFWF7CCX2:7:1108:17939:71770 1:N:0:TAGGCATG+CTCCTTAC

...

If I specify the '-no_qual_header' option in my Prinseq command line, we obtain for this read:

@ST-E00181:926:HFWF7CCX2:7:1108:17939:71770 1:N:0:TAGGCATG+CTCCTTAC

...

with a supplementary and false line. And there are many errors like this one...

No problem if I don't use this option (but files have a bigger size).

I know the Prinseq  software is a "old" tool but some biologists like it (and use it )...

Best regards,
