[Chimera-users] Splitting surfnet surfaces and calculate enclosed volume.

[Tom Goddard]

Hi JD,

  You can split the surfnet surface into separate selectable pieces by 
selecting the whole surface (ctrl-left-button) then using keyboard 
shortcut "Sc" (split connected pieces).  You have to enable keyboard 
shortcuts with menu entry Tools / General Controls / Accelerators On.  
After this you can select individual pieces and measure their volumes 
with the "mv" shortcut.  You can select all of the pieces and use "mv" 
to get a list of volumes for all the pieces.  "ma" lists areas.  Each 
piece is numbered and you that number will be shown in a pop-up if you 
the mouse over it.

  You can run the measure volumes shortcut  (mv) from Python code using:

import MeasureVolume
MeasureVolume.report_selected_volumes()

This code is in your Chimera distribution in 
chimera/share/MeasureVolume/__init__.py.
