[Chimera-users] Failed surface calculation

[Ibrahim Moustafa]

Dear Chimera,

 I¹m trying to calculate the surface for a protein but I get an error
²Surface calculation failed, mscalc returned code 5².
I tried to change the probe size from 1.4 to 1.5 or 1.7 but still getting
the same error. I know there is some issue with
The code that calculates the surface (if I¹m not wrong) but I wonder if
there is a way to get around this. For some smaller pdb files I don¹t have
this problem.
I¹m not sure if the size of the protein is a factor here. The protein having
the problem is a single chain protein with 880 amino acids.

Any advice?

  Thanks for help.
 Ibrahim
