Since distance restraints are added to the topology of one molecule, I believe than can only be applied intramolecularly.
Justin is right, it has to be intramolecular, but you can merge the two
topologies in one and then add your distance restraint.
try: pdb2gmx -merge

  Is there any way I can put distance restraint between atoms of two
different molecules?

Thanks in advance!

Hi,

I want to put distance based restrain between few pairs of atoms during
initial dynamics (along with Lincs on hbonds). I don't know how can I do
this.


Section 4.3.4 of the manual is probably a good start.

I will highly appreciate any suggestion.

Manoj
