[Gmod-ajax] JBrowse wiggle file display - png

[Shankar A. S. <sha...@gm...>]

Hi,

I'm a newbie to JBrowse and I was wondering if someone could help me
out with my question. I currently have a de novo genome assembly on
which I'd like to overlay wiggle tracks from RNA-seq data. The wiggle
file (variableStep) has values that are in the range 1-275000. This
(huge) range of values is probably why most of the regions appear to
be without any reads/expression - the low values are probably not
rendered in the png image.

I'm wondering if there's a solution to see the data at a better
resolution/scale. Are there options while converting to json that I
can use to make it appear better? Is dynamic scaling possible as a
user zooms in/out? Or should I do my own scaling/transposition before
I do the json conversion?

Thanks,
Shankar
