Dear Justin
It is obvious that emtol value can not be zero or negative. but you wrote in
your email " For more sensitive calculations like free energy simulations and normal modes, you will want to minimize much more thoroughly (for NM, emtol < 1) and in double precision". what did you mean by saying emtol<1? Anyway, my question was: for free energy calculation in double precision, what should be the best value for emtol?
Best Regards
Kiana

interaction. According to your answer, for more sensitive calculations like free energy simulations and normal modes, emtol should be lower than 1. As I understand, you mean that for these systems emtol should be 0 or negative. Is it really true?
