Subject: AMBER: Mutual exclusion of atoms

Dear Amber community,

 I have to build a system where I want that a set of atoms should not
"see" atoms from another set ie., they should be mutually excluded. I
know this is done in CHARMM by declaring explicitly, next to the
definition of each atom from one molecule, those atoms of another
molecule with which it should not interact. I need to carry out free
energy perturbation where I need to change one molecule into another.
So, I want to exclude atoms belonging too the initial molecule from
those in the final molecule.

Is there a way in amber where I can specify this? say by modifying the
prmtop files under "%FLAG NUMBER_EXCLUDED_ATOMS"

What is the format of doing this?

thanks a lot in advance,
Best regards,
Nitin
