From the user guid book, I learned that for a dihedral style of charmm, a dihedral_coeff command like this is required:
dihedral_coeff 1 120. 1 60. 0.5
But, the charmm dihedral style sometimes uses multilines to specify dihedral coeffs, like
ON5 CN6 CN6 ON5 0.3 3 0.0
ON5 CN6 CN6 ON5 -1.93 1 0.0
My question is how to write dihedral_coeff in an input file in this case?
Does the following command right?
dihedral_coeff 1 0.3 3 0.0 1.
dihedral_coeff 1 -1.93 1 0.0 1.
I could not find any instructions in the user guide book.
I would be grateful if someone could give me some advice.
