All of this information is in the manual, Chapters 4 (definition of
functional forms) and 5 (implementation in the topology). Force
field-specific concerns should be addressed in the literature.

Re: [gmx-users] Function of dihedrals in top file

2013-03-19 Thread Shima Arasteh
As I found up to now, func 2 is related to improper dihedrals. How can I find 
improper dihedrals? Can I not add them?


 
Sincerely,
Shima

 Dears,

There is term of function for each 4 atoms in dihedral section in top file. How 
this function is defined? To add extra dihedrals manually, I need to add 
function too.

Thanks.

Sincerely,
Shima
