Hi Tyler,

The Chimera Segger segmentation tool currently doesn't report the geometric center of segmentation regions or the principal axes. I've attached a Python script that will do that. Select the regions in Chimera then open the script (File / Open). The results will appear in the reply log (menu Favorites / Reply Log). The results are in physical coordinates (taking account of volume grid spacing), not grid index units.

Dr. Meng,

I am using Segger in Chimera and displaying the principal axes for some of my segmentations. I am wondering if there is a way to find the XYZ coordinates of the origin of the principal axes for each of my segments. Is there a way to put the coordinates for these axes in a text file?

Thank you,

Tyler Steele
