Downsampling bam files
WebDownsampling alignment BAMs RseQC is a standard tool for checking the quality of read alignments, providing the principal measurements of RNA-seq data quality. An RseQC tutorial is available here. To reduce running time, we first sub-sample sorted BAM files to be used by RseQC to assess alignment quality. WebSince some programs can't handle insane coverages, I would like to downsample, that is pick say 1000 aligned reads for each position randomly (E.g. with bamtools random: Select random alignments from existing BAM file (s)) but I need to keep the mates intact.
