Hi,
I think what you might want is parmed- you can add dihedrals by addDihedral, and I think you can add bonds/angles by setBond and setAngle? It's been a while since I've done it, but an example for an extra dihedral could be like
addDihedral :9.N1 :1.C6 :1.C5 :1.C4 0.0 2.0 1.2
Best,
Kenneth

Subject: [AMBER] Modifying prmtop/inpcrd files
Hello all,
If I suspect my prmtop file is missing bond/angle parameters etc, is there a way to manually add these in here if I'm unable to parameterise these with leap? If so, are there resources available online to help guide through all the information present in the prmtop file?
Thank you in advance,
Sam
