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

MD Movie (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)

Hello all!

It is possible to open the MD Movie trajectory with a custom format and a file from a plugin?

I am trying to do this:

from Movie.gui import MovieDialog
from Trajectory import EnsembleLoader
EnsembleLoader.loadEnsemble(MovieDialog, movieFile="/Users/ME/Desktop/movie.pdb")
​But I get this error​


ValueError: Unknown trajectory format: 'MODEL        0'

  File "/Applications/Chimera.app/Contents/Resources/share/Trajectory/EnsembleLoader.py", line 131, in loadEnsemble
    raise ValueError("Unknown trajectory format: '%s'" % format)

See reply log for Python traceback.

​I think it is because I need to set the format (self.curFormat in the EnsembleLoader class) but it is not possible. How can I solve this?

Thank you so much​
