[Chimera-users] Temperature during chimera minimization (pdb)

Minimization does not use a temperature. In molecular dynamics there is a concept of temperature from the kinetic energy put into the system, but this is not done in minimization. Sometimes the minimized state is described as “zero Kelvin,” but that may be an oversimplification. It only depends on the force field parameters and force field equation.
I hope this helps,

I am not sure chimera performed minimization at 273K or 298K. Could any one suggest me at what temperature chimera performs minimization (with explicit solvent), is there is a way to set different temperature.
