Hi Filipe, together with James' comment (thanks, James, too!!) "Once you have the cubes in CCP4 format you should be able to use coot to align the maps after aligning two PDB files corresponding to the coordinates of interest. Its the "Transform map by LSQ model fit ..." menu under Map Tools..

Hi there, depending on the level of theory you use, there should be an electronic density matrix behind the electrostatic potential calculation. I think this is the best metric you can possibly have/define to come up with an index like ">60% similarity": subtract the density matrices and then u

Dear Paul, dear everyone, I need to compare two Gaussian Cube files (Paul Bourke's page https://paulbourke.net/dataformats/cube/ is the best description I could find), and my first approach would be a map correlation coefficient at the van der Waals surface. Does anyone know how to do this? Det
