Hi Meng,

 

I’ve run into this problem a few times when I wanted to calculate and show the surface of a pdb model.

I got the following on my reply log:

 

C:\Chimera\bin\mscalc.exe 1.400000 2.000000 1

Calculation of some surface components failed.

Falling back to single-component calculation.

C:\Chimera\bin\mscalc.exe 1.400000 2.000000 0

Surface calculation failed, mscalc returned code 5

 

Sometimes I managed to go around it by resaving the pdb file in Chimera, or removing some irrelevant chains. but other times it just doesn’t work. Any suggestions?

 

One particular file that gives me the problem is 1IGT from PDB. I’ve tried removing all the heteroatoms and water molec, for I only need the chains A, B, C and D.  but still the problem persists.

 

Thanks!

 

Cheers,

Sumitro
