Hi, can anybody explain me the different uses for the single and the
double precison packages. Are there situations that explicitly require a double precision package,
and situations when i can use a single precision?

Double precision energy minimization is normally recommended before doing normal mode analysis. If doing an NVE simulation is important to you, then with otherwise suitable choices of .mdp parameters, double-precision integration might give better energy conservation. Otherwise, you'd probably be wasting processor time.

Search the archives, this question has probably been asked before.
