Hi everyone,

I have a question regarding the rescaling of data in ChimeraX. 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!

Best regards,
Matt

Done. Added "surface transform" command to ChimeraX daily builds, not in ChimeraX 1.4.

New command has a few differences from the version in Chimera. It does not have the radius option. The default center if none is specified is at the center of the bounding box of the displayed part of the first surface.

Elaine, can you document the "surface transform" command? The previous comment describes some differences from the Chimera version.
