[Chimera-users] total sum of a map

Hi Mario,

   You can skip the "vop resample" command and just use "vop add"

     vop add #2,1

This will produce a new map using the grid of the fist specified map (#2 
in the example) and will interpolate the other maps if their grids do 
not align.  This is in Chimera 1.4, the current production release.
