At first blush, this seems similar to the issue described here: https://github.com/fidelram/deepTools/issues/447
However there are no overlapping (much less duplicate) regions in any of the bed files. I ran computeMatrix and plotHeatmap probably dozens of times using these same input regions in the past with no issues. Upon adding a few additional bigwig files to a new run I began to get the error above. The output looks as expected, just missing thousands of regions.
Things I've tried:
1) Changing the bed input to a single file or a merged file
2) Changing the version to 2.3.3 or 2.5.0.1
I'm in the process of slowly removing the bigwig files one at a time to see where the issue is coming from, but haven't found it yet. I've used all of the bigwigs sucessfully as input for Deeptools in the past but not in this particular combination. There is no additional error message indicating an issue with any bigwig file.
