Hi Francesco, An MD Movie "metafile" can be opened with File... Open or the command "open." It is a simple text file that has the same things you would normally enter into the MD Movie input dialog, for example: amber 500 1000 prmtop mdcrd ... if my AMBER input files are named prmtop and mdcrd, and I want to view only frames 500-1000. The reasoning is that most trajectory formats require more than one file and/or some other parameters to be entered. Also, in the case of a single PDB file (with MODEL/ENDMDL around each frame), the behavior is different if you open it as a trajectory (allows play-through) than if you just opened it as a regular PDB file (shows all frames together at the same time). <http://www.cgl.ucsf.edu/chimera/docs/UsersGuide/filetypes.html#molstruct> <http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/movie/movie.html#metafile> Maybe this metafile approach will be helpful.
