WebChimeric reads occur when one sequencing read aligns to two distinct portions of the genome with little or no overlap. Chimeric reads are indicative of structural variation. … WebOct 25, 2024 · In principle, it is hard to tell. Bwa-mem makes an arbitrary choice. Mappings flagged with 0x100 are multiple hits. Mappings flagged with 0x800 are from a chimeric alignment. So you could actually filter by flag. But I am afraid the output could include something you do not necessarily want to (since there is no specific flag for the split reads).
