Bug with read clipper and fix_misencoded_quality_scores option

kohrnbkohrnb Portland State UniversityMember

I was softclipping some 84-bp-long single end reads using the following command:

java -Xmx2g -jar /GATK_Path/GenomeAnalysisTK.jar -T ClipReads -I imput_file.bam -o output_file.bam -R $ALIGNREF --cyclesToTrim "1-4,80-84" --clipRepresentation SOFTCLIP_BASES --fix_misencoded_quality_scores

There was no error while running, but when I looked at the file afterwards, every read had a cigar string of 84S. I'm fairly sure this is a bug. I was aligned to the human mitochondrial genome.

I am using GATK v2.3-9-ge5ebf34 on Mac OS 10.75
