Subject: AMBER: Problem with MacroMolecule to AMBER7

From: Guillaume Bollot (

Dear Users,
I have a problem with a macro molecule which contains organic and proteinic
parts. I used GAFF force field for organic (poly phenyls) part and PARM99
for protein but when I check my unit, Xleap give me an error message :
"Could not find bond parameters for : C - c...... etc....." for example.

My problem can be solved in AMBER7? Is it possible to combine force fields?
So yes or not how to do that?

Please help me because I don't any more what to do!!
Thanks a lot for your answers
