My qscript for GATK printreads walker takes very long time for gather function( BAM gather function) which uses picard mergesamfiles. How can I write custom gather function in qscript to improve the performance.
1. I want to try mutli-threading for picard mergesamfiles ( which is false by default)
2. I also to try simple concatenation of bam files (scattered bam files are already sorted)

    Unfortunately we don't have the resources to provide support for Queue-related development, so you'll have to figure it out on your own, sorry. Good luck!
