I have one Illumina sequencing fastq file where are several project sequences inside. Now I want to get only my experiment reads and so I added to the oligos file only my samples barcodes. But I think that confuses mothur, because it gives me segfault every time I try to run fastq.info. Is it a bug or do I have some other problem with my sequences?
