How to get trajectory frame each one nono second?

Hi,

I want to get trajectory frame each one nano second from 50 to 100 nano seconds. For example, 50,51,52,…
in separated files. I used gmx trjconv with -b 50000 -e 50001 to get one frame. Is there any option to get number of frames each one nano second? I am using bash script to analyze each frame and finally take the average of results but I need just one frame each ns.

Thanks, in advance

Add -dt 1000

Thank you dear Masrul

Is there any way to have each frame in separated files?

I would use -skip here instead of -dt. You can then write each snapshot to its own coordinate file with -sep.
