WebSep 30, 2024 · If a read can map to an alternate contig, then it is mapped to the alternate contig as a primaryalignment. For those reads that can map to both and align better to the ALT contig, the tool flags the ALT contig alignment record as supplementary(0x800). This is what we call alt-aware mapping or alt-handling.

Expectation maximization is used to probabilistically assign reads to isoforms. See the Cufflinks documentation for details and paper links: http://cufflinks.cbcb.umd.edu/ Best, J.
