ReadBackedPhasing of trio with 3 bams

sboylesboyle Bay Area, CAPosts: 28Member

I have applied PhaseByTransmission on a trio with a ped file and now want to run ReadBackedPhasing. However, each of the trio variant calls were called from a different BAM file (as each was from a different individual). In the ReadBackedPhasing documentation it only mentions using the program with a single bam. Does this mean that I need to merge the bams for each of the three individuals into a single bam? If so, do you have any suggested programs that work well with GATK?

    No, the documentation is just presenting the simplest case. Most if not all GATK tools that accept bam files will take any number - just specify -I multiple times or give it a text file listing all the BAMs

    Just beat you to the post button, that's all. @sboyle, don't forget to include the -respectPhaseInInput argument
