[Chimera-users] Coulombic ESP on multiple models

Hi Dan,
I wasn’t able to reproduce this problem.  I just tested in Chimera 1.10.2 on 3 related proteins, with commands:

open 2mnr
open 1muc
open 4enl
delete :.b
mm #0 #1
mm #0 #2
tile
surf

… then invoking Coulombic Surface Coloring, just clicking Apply because all three surfaces were already chosen in the dialog. Image of the result attached (after applying publication preset 1).   

I can’t think of any reason your system would behave differently, and all I can say is to make sure all the surfaces are chosen in the dialog.  However, if that still doesn’t work you can always try submitting a bug report (menu: Help… Report a Bug) and attach the session so we could try to reproduce it.

Best,
Elaine

We are trying to analyze multiple DNA binding proteins simultaneously (via matchmaker) and looking to visualize the surface electrostatic potential of each structure as a tiled picture. We are deleting the nucleotide chains for all proteins when complexed with DNA.  However, I am only able to get the surface electrostatic coloring for one structure (the reference structure), subsequent structures will not apply the columbic coloring after i hit apply, they just maintain the monotone default surface structure .  Could you please help me with this issue.
