Thank you, Bruno and Tsjerk. I found both approaches work very well. Eric Frankly, with Pymol, people don't as far as I know. What I usually do is determine for the first frame of the individual pdb files (obtained with trjconv -sep) the orientation, viewing point and appearance. This I save

Hi Bruno, Sure I'm aware of that, but for a bit of a system (as I usually have) and a good bit of trajectory (as I usually have), that will ask for quite some memory. Did it a few times, but prefer to use separate pdb's instead. Though admitted that for small systems, a multistate pdb works great

Hello, It's possible to convert to a single pdb file containing all the frames using: trjconv -f cpeptide_md.trr -o trajout.pdb -s cpeptide_md.tpr You can then load it into pymol using: pymol trajout.pdb And it will load all the frames. If you render a movie into png you will have lots of

Hi, I wonder if people can give a summary of how pymol makes movies out of gromacs trr (or xtc) files without having to use all the individual frame pdb files. Thanks! Eric
