[gmx-users] HOW TO EXTEND A .XTC FILE ??

[sky sky]

Hello. I am running the MD simulations for 100ns using GROMACS software. Now, I have a .xtc file and  I would like to extend my simulation but not from final step. Could anyone suggest me how should I extend this .xtc file from specific frame for another 100ns and when it ended I just have one .xtc file? it has a command? How should I proceed? Thank you in advance for your suggestions.
