I'm using SiteHound for ligand binding identification sites. I'm comparing the highest affinity sites for two superimposable receptors. I'm attaching an example where the sites favourable to protein 1 are shown red, whereas those for protein two blue.

I've opened in Chimera the file that contains the red and blue clusters (difference.pdb) as well as the corresponding potential file (potential.dx). I used the Volume Viewer to different affinity areas but had .... no luck.

Any help would be greatly appreciated

Best regards

George
