hi lina,

please always include the mailing list in your responses (click on
reply-to: all). this way other people with the same question can see
how your issue is been resolved and don't have to ask again. thanks.

there are too many to name. i can't describe the structure of the NAMD
code quickly in an e-mail. you have to read and understand it. sorry.

sutton-chen is a manybody potential and because of that you'd have to
make some significant modifications since NAMD as such only supports
pairwise additive potentials. that is why you would need to understand
the flow of control and how it is implemented using charm++ as
parallel computation infrastructure.

it would be simpler to use an MD code that has it already implemented
(GULP?) or adjust a code that has a similar potential implemented (if
i remember correctly, the EAM implementation in LAMMPS is a superset
of sutton-chen).
