[gmx-users] Catenation error

[suniba]

Hello experts and users

I have performed 4 simulations of same system starting with different initial conformations. Now when I am trying to catenate the trajectories with gmc trjcat, It is showing error that can’t catenate multiple trajectories with different number of atoms. I am not sure why the atom number is different since the system is same in all cases. 
With Regards
