<html><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;">Hi Dan,<div>I wasn’t able to reproduce this problem. I just tested in Chimera 1.10.2 on 3 related proteins, with commands:</div><div><br></div><div>open 2mnr</div><div>open 1muc</div><div>open 4enl</div><div>delete :.b</div><div>mm #0 #1</div><div>mm #0 #2</div><div>tile</div><div>surf</div><div><br></div><div>… 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). </div><div><br></div><div>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.</div><div><br></div><div>Best,</div><div>Elaine</div><div><div>-----<br>Elaine C.

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.<br><br>Thank you very much,<br>Dan<br></blockquote><br></div></body></html>
