Dear Charmm users,

I am using the KB GO model for a multichain protein.
When I read the topology and parameter files for the trimer (1758 residues) it gives, (I obtained the inputs from MMTSB server)
PARRDR> WARNING for bond, angle, dihedral, and nbond doesn't exist error.
This error does not appear when using the monomer (586 residues) and dimer (1172 residues).
Below is the code I used,

dimension chsize 2000000 maxnb 500000
STREAM go_trimer.param

I wonder why this happens!
My charmm version C45b2
Thank you.
