OK, plugins updated even though I do have the coordinate file. But I still can't display the MSMS surface. So here's what I did:
1) Converted .pdb to .xyzr
2) Started VMD 1.8.3
3) Within VMD console:
vmd > msms -if foo.xyzr -of test
MSMS 2.5.5 started on xxxxx.yyyyy.lu.se

So, now I'v got the files test.vert and test.face
and my coordinate file foo.pdb.
I can load the pdb-file into VMD but it doesn't visualise the MSMS output when I choose "Drawing method" MSMS in the Graphical Representations. I also tried loading the .vert and .face files via File-New Molecule in the VMD mail window but VMD don't accept that. What am I doing wrong?
Thanks in advance!
Best regards
Peter
