Dear VMD users

I got a polymer structure built from Materials Studio and prepared the
LAMMPS input data. [cross linked polymer, which contains several monomers ]

Using this LAMMPS input data (atom style : full), i created pdb and psf
files using TopoTools.

In these pdb/psf files, multiple resides have same residue number [resid].
[ it would have been good to have one residue ID for each monomer]

When i am trying to solvate this polymer using VMD, it produces an error
"Molecule destroyed by Fatal error", i think this could be because of
multiple residues having the same resid..

Could you please suggest if i can change the residue numbers [reassign
residue numbers starting from 1, so that each residue can have unique ID]
using some procedure..

one thing i tried using the commands from Axel's website shown below.
However this did not result in any change in the residue numbering. I
assume that VMD generates its own numbers for residue IDs starting from "0"

set resid {}
foreach r [$selc get residue] { incr r; lappend resid $r }
$selc set resid $resid

Thank you
best regards
Anki

 Please find here part of the PDB file i am working on, here the residue ID
"2" is repeated. Like this there are several residues with "2", "5" ....
