WebAug 25, 2015 · Look in the samtools specification... pretty sure there is some type of flag for multiply mapped reads. Then you can convert the file to SAM format and grep -v it. If the SAM/BAM file has secondary mappings recorded (which not all mapping software will do), then yes, you can filter them out using the FLAG bit values. Websamtools stats collects statistics from BAM files and outputs in a text format. The output can be visualized graphically using plot-bamstats. A summary of output sections is listed below, followed by more detailed descriptions.
