Hello,

I'm studying a protein in water at 348 K. In the equilibration phase (nvt, 1
ns) the temperature starts at about 348 K, and i can't see the slowly
increase of the temperature. I can't understand why the temperature is so
high at the beginning.
Could anyone help me?


Your question doesn't make much sense. If you're studying a system at 348 K, then the temperature starting at 348 K and not increasing all sounds right. Under the influence of a thermostat, the temperature should oscillate about the desired value. If something is anomalous, please provide better evidence and a full .mdp file.
