[Chimera-users] total sum of a map

Hi all, I try to multiply two maps in chimera. At the moment my workflow is the following: *open my two maps in chimera and try to fit map into map... *then I use "vop resample #1 inGrid #2" to set the same orientation *after this step, I convert the mrc files to Imagic and do a total-sum *what I get is one volume. Isn't there a way to do this in chimera? Thanks to all for any suggestions. Kind regards Mario
