I have equilibrated a protein solvent system using NVT ensemble and V -
rescale thermostat. Target temperature was 300 K.
Now I want to establish a temperature gradient in my system as follows :
1. Use Two Berendsen thermostats separately for Protein and Non Protein
Protein grp , T = 400 K
Non protein grp, T = 300 K.
Run in NVT for 100 ps.
2. Then remove thermostat from Protein grp. But keep thermostat for Non
Run in NVT for 500 ps. I hope that the protein will come down or relax to
Is the above scheme feasible ? I have not yet tried.
I use COM motion removal for the whole system.
