I have ~ 3 GB GMX .trr trajectory file and I canno load all of it due to memory so I use stride. I want to save the whole trajectory without striding it. For NAMD trajectories I know I can use the following tcl script
mol load psf pr.psf
animate read dcd pr.dcd
[atomselect top all] writedcd pr.dcd

But for GMX - where I use pdb and trr files instead of psf and dcd - how can I do it
