Hi, check the standard options of mdrun with the help flag -h of version 4.5.4 and below. You will realize, that the standard append behaviour changed from "no" to "yes". Hence if you start from a checkpoint and files are already present in the working directory the integration results will be appended. /Flo > Hsin-Lin > -- Florian Dommert Dipl. - Phys.
