[Chimera-users] need coordinates from volume data

[Tom Goddard]

Hi Terry,

   I've attached some example Python code to find the (x,y,z) 
coordinates of volume grid points.  The output  after opening this file 
in Chimera (shown in the Reply Log (menu Favorites / Reply Log) looks like

read map 1a0m.omap
data size 91 95 82
xyz for index 15 7 13 is 2.96 -7.4 -1.46875
data value at ijk 15 7 13 is -0.381388

I put this example on the Chimera Python scripts page as readvol.py.
