<p class=MsoNormal>I wanted to contact you about the surface representation of
a protein. I used to be able to show the surface of our protein and
lately I can’t show the surface on most multiple subunit proteins because
the calculation fails. However, I noticed that on some previously edited
structures (the same one as before, except I deleted some of the subunits/ligands)
that the surface calculation would work. So, I started deleting lines in
the PDB file to see if I could get the surface to start working. Sure
enough, when I got to only 1 subunit left, it worked. So after more
investigation, I found that if I insert “End” between each of the
subunits/ligands in the PDB file then the surface calculation works for the
whole structure. I have seen in the release notes of Chimera that some protein
surface calculations fail, so having found a way to get mine to work, I thought
I would pass it on in case it could shed some light on this surface calculation
issue. Or if you have another idea how to “fix” this issue I
am having, I would be glad to hear about it. Finally, I wanted to let you
know that I thoroughly enjoy using Chimera, it is a great tool. Thanks.<o:p></o:p></p>
