[Biopython] ResidueDepth msms.exe has stopped working

[Ahmad Abdelzaher]

Hello,

I get msms.exe has stopped working from windows,and "AssertionError:
Failed to generate surface file using command:msms -probe_radius 1.5
-" in python console.

I tried it with a different pdb, same result.

The code is here:

from Bio.PDB import PDBParser, ResidueDepth

p = PDBParser()
s = p.get_structure("X", '1crn.pdb')
model = s[0]

rd = ResidueDepth(model, '1crn.pdb')
print(rd[(chain_id, res_id)])


I'm really stuck here, i would appreciate any prompt help.

Regards.
