[chimerax-users] Rescaling IMOD segmentation models in ChimeraX

Hi Matt,
ChimeraX does not have any way to scale the size of a surface model such as an IMOD segmentation. It could be hacked with a bit of Python opened in ChimeraX. But it is usually best to have your data files encode the proper scaling in their header so I would suggest fixing it in IMOD.
Our older program Chimera has an "sop transform" command that can scale surfaces

Maybe I could port that to ChimeraX. I agree it is sometimes useful.

I'm depicting a subtomogram average at their aligned positions in a tomogram, which doesn't contain scaled pixel information, and I want to also load in IMOD segmentation data to depict with the subtomogram average. I'm able to readjust the pixel size of the tomogram easily with the Map Coordinates dialog box, but is there a way to rescale IMOD segmentation models once in ChimeraX? I can do this within IMOD, but it would be more convenient to do it in ChimeraX with the volume. Thanks in advance for any help!
