Hi Kyle, Now there are Chimera commands to color zone and split by zone, so you could use them directly or via the python approach to run Chimera commands. http://www.rbvi.ucsf.edu/chimera/docs/ProgrammersGuide/basicPrimer.html For color zone, see “scolor zone” http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/scolor.html Splitting a map by the resulting color zones is a little harder to find because it’s not a regular command but a keyboard shortcut “sm” … however, it can be run with the regular command “ac sm” http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/midas/ac.html http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/accelerators/alist... I hope this helps, Elaine ----- Elaine C.

Hi Chimera dev, Following on from this post back from 2009:

How would one also split map in this python script? Thanks! Kyle
