[gmx-users] correcting timesteps

[Leigh]

Hello

I fudged a restart on gromacs 2018 and am missing 195 femtoseconds from my
trajectory. This shouldn't matter because I only need a 10 picosecond
resolution trajectory. However, when I try to correct the timestep with
trjconv and -timestep it doesnt seem to have done anything.

*gmx trjconv -f 40t84_10p_concat.xtc -timestep 10 -o
40t84_10p_concat_10.xtc*



This command worked but when running *gmx check*  on the new trajectory
afterward there are still a bunch of timesteps don't match errors.


gmx check -f 40t84_10p_concat_10.xtc
