[gmx-users] How to extract frames from a simulation at regular intervals and make a new trajectory?

[Prasanth G, Research Scholar]

I am interested in extracting 300 snapshots from a 30ns simulation with an
interval of 100 ps and create a  new trajectory for analysis (MMPBSA).
files md_0_30.xtc, md_0_30.tpr..
new trajectory to be named as md_analysis.xtc.

Request you to help me in this regard.
Thank you.
