Re: [gmx-users] Single long simulation versus multiple short ones

2011-07-25 Thread Tsjerk Wassenaar
Hey Widya, In general, no, 15*2ns is not equal to 1*30ns. The reason for this lies in correlation and relaxation times. 15 simulations of 2ns give good statistics on relaxation and, if the system is equilibrated already, on short-term processes. A single simulation of 30 ns may relax to equilibriu
