No problem :)
The equilibrium protocolo is an art.
Usually I run equlibration using the following steps:
1.minimization of water using a constrain force of 500kcal on protein.
2.minimization of the whole system (i.e. without constrain)
3.100ps of NVT MD at 100 Kelvin, timestep 1fs
4.100ps of NVT MD at 200 Kelvin, timestep 1fs
5.100ps of NVT MD at 300 Kelvin, timestep 1fs
6.100ps of NPT MD at 300 Kelvin, 1bar, timestep 1fs
Production run: NPT MD at 300 Kelvin, 1bar, timestep 2fs
