Graphics crash when DICOM has unexpected size relative to other images in same dataset

[Zach Pearson]

The following bug report has been submitted:
Platform:        macOS-13.2-arm64-arm-64bit
ChimeraX Version: 1.6.dev202303032252 (2023-03-03 22:52:18 UTC)
Description
The attached TCIA dataset causes ChimeraX graphics to crash, both when trying to display the DICOM as a surface and when moving the volume viewer plane slider to the last position, presumably because the last image in the dataset is so much bigger than the others.

'graphics restart' also doesn't seem to be affecting the volume viewer after a crash like this. I can open proteins and spin around new DICOM planes, but I can't change the display mode (surface, mesh), and attempting to change the plane shown has no efect, and neither do the level controls.

[Tom Goddard]

This error message means that the DICOM volume data GridData object is reading 234256 values for one plane of the data which is not the right number of values for a 168 by 168 plane.

ValueError: cannot reshape array of size 234256 into shape (1,168,168)

So the trouble is that DicomGrid claims the data size is 168 by 168 by 33 and yet its read_xy_plane() method returns a numpy array that is not 168 by 168 in size. So this is a problem with the DICOM reader using a wrong grid size.

[Tom Goddard]

When we use the word "crash" in bug reports we generally mean the program exited (e.g seg fault). This report is not a crash, just an error giving a Python traceback.

[Zach Pearson]

I was surprised to learn that DICOM series can have files of different sizes. Indeed 16 files in this 17 file series are 168x168, the last one is 400-something x 400-something. I think we can get around this by having the Series class segregate files by size, then open different grids for each one.

[Zach Pearson]

It took a sizable refactor to enable this: the Series code has to sort the files by size then open different DicomData objects for each one. Those DicomData objects then need all of the attribute derivation code that used to be in the Series class to figure out how to make themselves into valid grids. I don't think it should be backported to 1.6. I'll add some code to the 1.6 codebase to detect when these datasets come in and warn the user that viewing those slices may cause drawing to stop.

[Zach Pearson]

I ​pushed a commit that implements that refactor.
