it does if they are within the normal distance. are your pdb files ok?

I want to force some disulphide bond and simulate the structure to compare 
both (with and without the S-S bond). I was wondering if GROMACS can use 
SSBOND in pdb files directly. I'm writing some scripts using Expect language 
but at the moment I'm stucked with some TCL stuff.
