[gmx-users] question about dihedral angle in *.itp file

[linfu]

Dear GMX community!

I have a question about dihedral angle in *.itp file.
question 1:

why several torsional dihedral angles with different parameters can be defined
on the same set of atoms i, j, k, and l.

question 2:

how do we get multiplicity m if we want to make some parameter for some torsional 
angle.

Thank you very much!
