Dear Professor Simmerling,
Sorry for being so obscure. I will try to reformulate my question in a clearer way.
Basically I would like to know whether in NEB calculations, as far as the force constant is concerned,
the selected part of the different replicas can be regarded as a single effective "atom" or the force constant refers to
individual atoms inside each selected region. Also, I would like to know what is the appropriate value of the force
constant for a very large system such as mine (about 4000 atoms).
Thank you very much for your kind assistance.
best regards,
Maiti
