Gviz error message

Question

[ta_awwad]

Hi everyone, I would like to fetch data UCSC custom tracks using Gviz. Does anyone have an experience in this regards?

thanks a lot TA

Question unclear. A custom track on UCSC would mean that you added that yourself and you have access to the original data?

[ta_awwad]

yes but when I feed it directly to Gviz it doesn't look good as it is in UCSC although it is the same wig file. do you have an idea to improve it?

So essentially the problem is that your track doesn't look as you want it to, which is an entirely different question than originally.

actually, I managed to get nice tracks now .. however, Gviz doesn't like some wig files. it gives me the following error message: Error in .local(range, ...) : The import function did not provide a valid GRanges object. Unable to build track from file 'AG.wig'

the wig file looks good and I don't know how to deal with this .. I googled it but now good answers
