Platform:        Windows-10-10.0.19044
ChimeraX Version: 1.6rc202304272016 (2023-04-27 20:16:52 UTC)
Description
I was attempting to load data from TCIA collection CT Lymph Nodes, patient ID = ABD_LYMPH_019.  I think it might have failed in trying to load the SEG series with the CT.  Do you support DICOM SEG?

This dataset works in the 1.7 daily build. I refactored the DICOM module to accommodate datasets on TCIA that have differently-sized and oriented images in the same series (e.g. some PET scans), and thought it was a little bit risky to backport to 1.6 this close to a release. Can you retry the 1.7 daily build?

[Zach Pearson]

OK, this is a real bug that needed to be patched on both branches. I try to sort series by their number so that they show up nicely in the model panel, and I get the number from files with file.get("number", default). This will actually return None if the number happens to be None, but I've treated that syntax as if it means "1-if-not-x.attr" in a couple places. Will be patched tomorrow.
