I have hit a brick wall when trying to convert wig files from the GEO to bigwig files. Each time I try (and I have tried many times since October), I get the same error. For example, here is a downloaded wig file, that I assigned to the mouse mm8 genome, and the error I got when I tried to convert it to a bigwig file. The dataset came from Bing Ren's lab, and its GEO record is here: http://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSM560344

The wig file was uploaded to Galaxy Dec. 8, 2011, and I assigned mm8 rather than mm9 based on the GEO record:

~960,000 lines
format: wig, database: mm8

Info: uploaded wig file

display at UCSC main

The details for this upload are as follows:

The wig-to-bigWig conversion on data 49 (using the wig to bigwig conversion tool in the convert formats toolbox) was run on March 21, 2012 and gave the following error:

Wig-to-bigWig on data 49

I gather that the chromosome ends are not being snipped off, even though I toggle this option on the galaxy conversion tool. And I know it's doing something, because if I toggle that option off, I get an error that includes "broken pipe" and simply aborts. I apologize for knowing so little about the bioinformatics involved here. And I'm sure I've overlooked something that is likely obvious to others and/or failed to provide some critical bit of info in this email. But any help would be greatly appreciated.
