I want to extract n frames in pdb format from say, the last half of a gromacs trajectory. How do I do this?
This is when I have 50000 as my
nsteps in the
mdp file I used for running
grompp, before I did energy minimisation using
mdrun. I tried playing around with
-e arguments for
gmx trjconv but I get and error saying:
... trn version: GMX_trn_file (single precision) Last frame -1 time 0.000 WARNING no output, last frame read at t=474 ...
For example, I may get this error by running
gmx trjconv -f the-em.trr -o the-em.pdb -b 0 -e 400 -dt 10
