Hi Oliver,
Thanks for your reply.
Sorry for the confusion.
What I intend to do is to load for example the last 10 frames of a lammps trajectory file.
In VMD this can be done, with which I haven't had much luck:
`mol addfile out_test.data type lammpstrj first 1 last 5`
The reason I want to do it this way is that my dump file is huge, and I need to troubleshoot the job by looking at the last few frames.
Does MDAnalysis load the whole trajectory file into memory? Because it takes forever to make my `MDAnalysis.Universe` from this big trajectory file even with `in_memory=False`.
I guess a command like ` u.trajectory[-10:]` works when the whole trajectory file is parsed and the number of frames are known. So I guess my question is mainly for `MDAnalysis.Universe` stage and how make the Universe with a range of frames.
Please let me know if this didn't make sense.
Thanks.
