Dear All, I did the simmulated annealing for a protein where I wanted to increase the temperature from 0 K to 300 K after 300 ps. But after the simulation run I see the temp got increased up to 400 K and so. So can anyone tell me whether I am doing any mistake ? The .mdp file for the run is as follows. The temperature plot has been attached with this mail.
