Subject: [AMBER] Gaff compatible with ff899.SB

Dear members,

 

I read that gaff force field is compatible with the macromolecular force
fields like ff99.SB.

 

Atom types are lower case for Gaff and upper case for ff99.SB. How could
the non-bonded interactions be taking into account between a polymer
parameterized with Gaff and DNA parameterized with ff99.SB? How do these
two force fields "understand" each other in terms of electrostatic and
Van der Waals interactions?

 

Thank you,
