Dear AMBER team,
I am trying to estimate TdS of a 3000-atom protein using mm-pbsa and
nmode. My question is, what methodology is recommended:
1) Are some 3 snapshots doable in reasonable time on Opterons with 8GB
memory or Altix Itanium Medison with 32GB?
2) Using nmode, can I choose some parts (active site) for nmode? What is
the format for BELLY groups in mm_pbsa?
3) Or manually taking snapshots out of trajectory, minimize with
dist-dep. diel 4r: sander steep. desc+conj.grad to converg 10E-4.Select
active site only, minimize nmode Newt-Raph to converg 10E-4 then nmode
vibration analysis. At what stage is it best to start using the active
site only? Is it useful to apply some constraints in the Newt-Raph.
minimization?
Looking forward to your replies. Thanks.
Best regards,
Martin Lepsik
