W: Dihedral problem: %d %ld %d %d %d %d
Conformation of the 4 listed dihedral atoms is extreme; you may want
to check your simulation geometry.
E: Invalid coeffs for this dihedral style
Cannot set class 2 coeffs in data file for this dihedral style.
E: Incorrect args for dihedral coefficients
Self-explanatory. Check the input script or data file.
