I have searched the amber archives and found that some people have used
NONBON
Fe 1.2000 0.0500 (HEME)
My target is to look at the overall conformational changes in the protein and
not concentrating very much on the cluster itself. Is it advisable that i use
the parameters as from HEME for my system as well? Also i found that you have
been calculating the force fields for fe4s4 clusters. If you please suggest me
how to modify it for 3fe clusters.
Looking eagerly forward for your reply.
Thank you a lot.
