I have two bigwig files downloaded from GEO accession

GSM6757703 and GSM6757712

When I try to computeMatrix and plotHeatmap for these two bw together with some other bw files, I got the error of "No common chromosomes found" while I'm sure they are from the same species and assemblies (dm6), if I remove these two bw files from the list, it works. If I do the same thing for these two bw files alone, it also works to some degree, except that it's skipping 90% of my regions in the bed file (which works for other bw files), when these regions apparently exist -- they look normal in IGV browser in parallel with my other bw files.

Would anyone please help me check if these two bw files are problematic somehow and how to fix it? Thank you very much in acvance!

Error when these two bw files processed with my other bw files:

My bed file is also attached.

I realized that the chromosome lengths have to be the same among bw files, not only the names. The two problematic bw files had different chromosome lengths although they were mapped to the same assembly dm6. So I converted the bw to bedgraph, then adjusted the chromosome lengths to the same, then converted the bedgraph back to bw. Now everything works

[WardDeb]

To me this sounds like different subversions of dm6, and I'd be careful just changing these lengths, as your coordinates won't match anymore. Safest bet to make sure these are really the same reference is to align them yourself.. This isn't a deepTools issue, though.
