Hi, For some time now, we have found that wig files on the Penn State Galaxy cannot be transferred into the UCSC browser via the Galaxy URL. We receive the error: " Error Unrecognized format line 2 of https://main.g2.bx.psu.edu/datasets/329241/display/: (note: chrom names are case sensitive)". When we examine the file, the case is correct. Moreover, if we download the file and upload it to the UCSC browser directly from our computer, the data is properly displayed. A search of the Mailing List with the following phrase: "note: chrom names are case sensitive", brings up some discussion of this issue but I was unable to find a resolution.
