Subject: AMBER: force field question

I am using the ff03 force field for proteins and preparing a system for
constant pH simulations.
In p. 172 for the online manual, the ff99 force field is used, where in
particular the file
frcmod.mod_phipsi.1 is loaded.

The question is: has this change being incorporated in the ff03 force
field?. ( I got the file on line,
it is rather small, just a couple of lines). or do I have to load the
"changes" anyway?

Regards

Eddie
