Hey James,
So sorry for the late reply, in case I forget, you can also leave your
question/feedback ingithub issues page backlog
<https: github.com="" tengfei="" ggbio="" issues="">. I will work on those
backlogs
when I got time.
Are you looking for a normalization cross samples for
coverage? Unfortunately, it's not built-in yet.
But I am re-work on autoplot() for bamfile list for particular regions
now,
I will think about give options on normalization considering the
library
size. Or more flexible, you could use your own method to do
normalization
on the raw RleList, then autoplot will provide better/faster graphics
for
RleList after the improvements. This new features will be implemented
in
devel branch.
Let's keep in touch.
cheers
Tengfei
