Hi Suheila, The CMV requires the contact map and the structure to match. So to get what you want, it's easiest to load the structure in pymol, and save only the part you want to analyze:
save helix.pdb, ss h save sheet.pdb, ss s Then you can run g_mdmat on each of those, and load the result back in pymol. Hope it helps, Tsjerk On Mon, Mar 19, 2012 at 6:20 PM, Suhaila Haji Mohd Hussin <bell_beaut...@hotmail.com> wrote: > Hello especially for those who are experienced using Contact Map Visualizer > Plugin.
