Hi, gmx users:
when I used g_velacc to calculate VAF, I found the minimum of dt could be taken to 0.1 ps, but smaller. If I want to gain more precise results, how can I do??

I don't quite follow your question, but for correlation functions to be computed accurately, you need data collected much more frequently than the relevant time scales. That can require good planning.
