Goodness, sounds like fun.
Coot does have an align&mutate function of course, but you don't get to
fiddle with the sequence alignment - Coot uses its own alignment [1].
My understanding is that should be fine for ~70% sequence identity or
better. My feeling though is that it is not widely used. So my question
to the community is: Is there a need to be able to use an alignment
rather than simply a target sequence?
Thanks,
Paul.
