Hi Shengyou,

  The curvature.py script was attached to the Chimera mailing list message you found.

http://www.cgl.ucsf.edu/pipermail/chimera-users/2014-January/009580.html

It got renamed with a ".bin" suffix, so after you download you should change the file name to curvature.py.  A similar capability is in ChimeraX, the "measure convexity" command

https://www.rbvi.ucsf.edu/chimerax/docs/user/commands/measure.html#convexity

Here's an example image using "measure convexity #1" on EMDB 0074.

Hi Tom,


I just noticed that you had helped a user about "Coloring EM map by curvature" in UCSF Chimera through some scripts like the following

open 1grl 

	molmap #0 15 grid 2 model #1
	select #1
	open ~/Desktop/curvature.py
Could you please send me the "curvature.py" file or tell me where to download it?


Thank you very much for your help!

Best regards,


Shengyou
