Hi Jianhong and Julie,
When using browseTracks, I am unable to use some files once mounted if their extensions don't exactly match known strings. The following messages appears when importing bigwigs with ".bw" extensions, for example:
Can not detect the format of the file. Please rename the file with end of .BED, .bedGraph, .WIG or .BigWig
Is there a way to expand the library of recognizable extensions or assign an alias? Once mounted, it's very cumbersome to unmount, change extensions, remount and reload the relatively bulky dependencies like TxDb, org etc.
Thanks for the help!
