I’m unable to suggest a reason as to why this has happened, other than some sort of
corruption whilst the job was running, but I would point out two things to you.
1. I don’t think you need to run the fastq groomer on your data anyway as it’s in Illumina
1.8+ format, which should already be in fastqsanger format.
2. It appears that the fastq groomer hasn’t worked as the quality scores haven’t changed
format. (A general question to anyone here – will fastq groomer change the quality format
of reads that are already in fastqsanger format?)

Subject: [galaxy-dev] Error introduced with Fastq Groomer
Some unexpected symbols were introduced while grooming my fastq file
I relaunch this step without being able to reproduce the bug. Any ideas about this problem
? Have you guys came across the same problem before ?
