Hi, I'm using molekel 5.3 for Mac. I have two files with cube structure (from non-commercial program). One contains a grid of points and values, and the second information regarding which point belongs to which part of the surface. I would like to picture these surfaces with different colors, for which I need to map the second file into the first. How can I do this in the current version of Molekel? Such possibility existed for Molekel 4.1. I loaded separately both files and then I chose "Grid Value", automatically surface was colored by different regions. Either a way to solve this issue for Molekel5.3 or a version of Molekel4.1 for Mac (or with the source code so that I can compile it there) would solve my problem. Many thanks in advance, Eduard PS/ Please contact me by e-mail: ematito@gmail.com
