I want to equilibrate my protein in a water box, using PBC, ions, and
everything to set up my molecular dynamics.
I noticed water grouping during my equilibration dynamics NVT. (It looked
like many bubbles -spherical spaces without water molecules- in my box); I
guess that something it's wrong with pressure/volume since I didn't carry
on control pressure before i started the NVT run of production.
I had understood that a protocol it was minimize-heating-equilibrate
temperature (NVT)- and finally I will do a production run to evaluate
certain residues in my system as time evolves.
Is it recommended or is it necessary first equilibrate my system at
constant pressure and temp. NPT, before I run NVT equilibration?
and how NAMD controls density in a water box? because maybe it was a drift
Thank you in advance for any help...
