Hi Rodrigo! Happily, I can say yes there is a way. You can put the information that would have been entered in the initial MD Movie dialog into a small text file called "metafile" and then open the metafile with a command, e.g. something like:

open md:/Users/meng/Desktop/mymetafile

There is some description of this below the formats table in the "MD Movie" input section: <http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/movie/framemovie.html> ... specifically <http://www.rbvi.ucsf.edu/chimera/docs/ContributedSoftware/movie/movie.html#metafile>

See also "MD Movie metafile" in the general input formats table: <http://www.rbvi.ucsf.edu/chimera/docs/UsersGuide/filetypes.html#molstruct>

I hope this helps, Elaine ----- Elaine C. Meng, Ph.D. UCSF Chimera(X) team Department of Pharmaceutical Chemistry University of California, San Francisco

Hello! I wonder if there is a way to load an AMBER topology/trajectory directly from the command line without having to go to tools->Md/ensemble-> MD movie, etc...

For example, in VMD you can use: vmd -parm7 topology.parm7 -netcdf trajectory.nc

I am NOT implying VMD is better than Chimera :) It will be just faster to be able to quickly load trajectories from the command line to save some time.

Thanks! Rodrigo.
