Visualizing elastic network proteins

GROMACS version: 2022
GROMACS modification: No

I am working with a coarse-grained MARTINI system. My system contains a beta-sheet protein, which is modeled using an elastic network, and the bilayer contains MARTINI-3 lipids. I am trying to visualize the protein without an elastic network, for which I am giving the following commands in the TK console:

vmd > source /home/user/scripts/cg_bonds.tcl
vmd > cg_bonds -top vmd.top -topoltype “elastic”

But the error that crops up is: atomsel : setbonds: Need one bondlist for each selected atom

Tried searching a lot in the web but did not get a clue.

How do I solve this? Any help in this regard would be really helpful.
