Hi all,
I want to calculate free energy change during the process of insertion of
a molecules inside a pore.So I am planning to to umbrella sampling by
defining distance between COM of pore and molecules as the reaction
Now I am unable to figure out ,how to define this distance as my reaction
coordinate in my input file(DISANG).To be more specific,I have problem in
understaning iat(n) variable in &rst namelist.
Any suggestion will be appreciated.
