[chimera-dev] Open MD Movie Trajectorie from plugin

[Eric Pettersen]

The ‘movieFile’ argument to EnsembleLoader.loadEnsemble is expected to be a “metafile” as documented here:

MD Movie <http://www.cgl.ucsf.edu/chimera/current/docs/ContributedSoftware/movie/movie.html> (third paragraph after the first table)

So, one option is to use a path to a metafile as that argument.  To use the PDB file directly as the argument, you need to import loadEnsemble from the PDB format module, like so:

from Trajectory.formats.Pdb import loadEnsemble

Then call it as:

loadEnsemble((“single”, "/Users/ME/Desktop/movie.pdb”), None, None, MovieDialog)
