Bjorn,
I don't know if it can be done in AMBER; perhaps someone else can
comment on that.
However, I am still not sure the question you are asking is entirely
well posed. You might want to think carefully about what you hope to
get from this. You need a metric to define what "interacts" means, and
even given that, it is not entirely clear to me what you can get from
it. I guess you could say that the difference in the
bupivacaine-environment interaction potential energy is [some number]
between when it is "interacting" with MAA and when it is not. If
that's what you want, that's fine, it's just not clear to me how it is
physically meaningful.
