Bwa mem soft clipping

WebMar 29, 2024 · Q1. I am looking for a way to remove SAM alignments that have too much soft or hard clipping. eg. a 150bp read with 30S80M40S. I can't seem to find a way to do it with tools from the samtools toolkit. I can adjust some parameters to bwa mem like the scoring parameters like -L etc, but it's a bit hacky..
