`handle_header` mangles alt contigs #79

Closed jdidion closed 2 years ago

jdidion commented 2 years ago

When using a reference with alt contigs, contigs with names of the form "HLA-A01:01:01:01" are truncated to "HLA-A01", which produces duplicate contig names in the output. If bwa-meth is not designed to work with alt contigs, please state this explicitly in the readme, otherwise this issue needs to be addressed. Thanks.

My guess is that this is unintentional and can be fixed by adding maxsplit=1. I'll submit a PR.
