ReduceReads Unknown Contig

kylechbkylechb Boston Children's HospitalMember Posts: 4

Hello,

I am new to the field, so please forgive me if this has a simple answer. I am attempting to call variants on 6 whole exome sequences. The best practices documentation suggested using 30 or more samples, so I downloaded 24 bam files from the 1000genomes database to use with mine. However, whenever I attempted to use ReduceReads on the files, I received the following error right near 100% completion:

ERROR MESSAGE: BUG: requested unknown contig=NC_007605 index=-1

I am using the latest b37 reference file from the bundle, and I have tried re-indexing it and re-forming the .dict file. Here is the stack trace from the above error. What is causing this, and how do I fix it?
