Dear All, dear Eric, After concatenating the trajectories, I noticed that the last frame of the (i-1)-th trajectory file (in xtc format) and the 1st frame of the i-th trajectory file are identical. Is it possible to remove this duplication?

I see now that the information is in the ChimeraX help files under "open" but I was looking under "trajectory" so I was not able to find it.

With the command, add the option “replace false” to append the frames to the existing ones instead of replacing them, --Eric Eric Pettersen UCSF Computer Graphics Lab On Mar 28, 2025, at 8:05 AM, Alexandra Zahradnikova via ChimeraX-users <chimerax-users@cgl.ucsf.edu> wrote: Dear All, I am new in molecular simulation and not very much experienced with ChimeraX. I did not find an easy way to concatenate trajectories (in my case, .xtc files from gromacs). Any suggestions would be welcome.
