[gmx-users] how to set tolerance for bond formation distance?

[Uwe Richter]

Hi,

it's not quite clear what you mean. Gromacs doesn't  look at distances
to define bonds except for special bonds listed in the file specbond.dat.
Use chain id's in the pdb file. Otherwise chains will be connected no
matter what the distances are.
