[Chimera-users] vop binning

[Thomas Goddard]

Hi Katrina,

   The vop command is written in Python code included with the Chimera 
distribution in directory

	chimera/share/VolumeFilter

(on Mac in Chimera.app/Contents/Resources/share/VolumeFilter).

   The code that actually sums the values for the bins is in bin.py in 
that directory.  Not very interesting.  Probably pretty complicated 
looking because it handles subregions, subsampling, variable bin size.

   If you give more details of the volume data analysis you are aiming 
for I might be able to give you some more relevant example code.  The 
Chimera Python scripts page might have something useful, for example, 
the iterpolate.py script:
