Dear Daniel
Thanks, one quick question. My earlier simulation upto 50 ns was with iwrap=0 and now I am using netcdf outputs with same iwrap=0. Considering netcdf has much precision; so does that mean I can not "combine" as a regular plot, e.g. some function (say diffusion) vs time, of intial 50ns less precision traj (iwrap=0) with later more precision traj (netcdf).
regards
J

Hi,
You should definitely use NetCDF trajectories since they have better precision and are faster to process. Note that you can also post-process an imaged trajectory with the 'unwrap' command; this will make the trajectory as if you had simulated with iwrap=0.
Hope this helps,
