[Chimera-users] OS X aqua version

[Thomas Goddard]

Hi Jean-Paul,

   Chimera cannot subtract two maps.  Is that what you had in mind? or 
is it more complicated requiring determining equivalent normalizations 
for the maps?  Do you have in mind that the maps have identical grids, 
or would one map need to be interpolated?  There's underlying Python 
code to do all this in Chimera but no user interface.
