Hi Agnivo; Yes, the idea of freezing the solvent or the protein in many times is to sample the "non-equilibrium thermal process". It will remain in the target temperature on average, over many fixed configurations obtained by different NVT runs (equilibrium runs). But you may need to run this many

Hi Agnivo, Temperature gradient means non-equilibrium MD (NEMD) See notes from Prof. Martini: https://nanohub.org/resources/7582/download/Martini_L10_NonequilibruimMD.pdf What observable would you like to measure? Lets say you want to measure observable A. One "procedure" I can think of: 1. Y
