N+n MM tag display bug #1444

Closed AlexCalderwood closed 11 months ago

AlexCalderwood commented 11 months ago

Hello,

It seems that positions tagged using the MM base-modification tag N+n (see https://samtools.github.io/hts-specs/SAMtags.pdf top of page 9) overflow the coverage track when select colour alignments by > base modification.

That's not surprising, this is the first N+n example I have seen. I will get to this when I can.
