If your system contains a lot of water, you might want to have a look at the catdcd tool to write a trajectory containing only your atomselection, so you might be able to load it at once to VMD. Away from that, you could write a TCL script which loads frame after frame and renders the image. Later you can combine all the images to a movie file. The movie maker in fact, follows the same procedure but instead has all frames loaded already.

Betreff: vmd-l: making a movie of a atomselection of a very large trajectory

 

Dear all,

I have a very large trajectory file (about 40 GB) so that I can't load it at once on vmd. I want to make an atomselection, update it every frame and I want to play the motion of atoms in this atomselection. I wrote a pdb file which contains the atomselection in each frame using "animate". Can I use the same command to play the trajectory of these selected molecules only? The examples I found talk about loading the trajectory at once and then make atomselections so if you can give me any suggestions it is greatly appreciated.

Thank you.

Monika
