Hi Matt, Support for DCD trajectories is in our current Chimera development version, but is not in the most recent release, Chimera 1.1951. It is described in the development version of the Chimera manual: http://www.cgl.ucsf.edu/chimera/docs/ContributedSoftware/movie/movie.html If you like, I can give you the new Python code for DCD trajectories. I have not yet tested whether it will work in Chimera 1951, but I can test it. Otherwise, you can get it in our next release which is at least a few months away. To reposition a PDB model using Python code see the Programmer FAQ: http://www.cgl.ucsf.edu/chimera/docs/ProgrammersGuide/faq.html#q4 Tom

Tom,

Two quick questions: 1. Is there a reader/display for DCD or netCDF trajectory files in Chimera? I see that you can read AMBER trajectory files in the Molecular Dynamics module.

2. How do you update a PDB file loaded into Chimera? I have a PDB file and I want to apply a transformation to it and have the updated coordinates applied in the viewer.

Thanks,

Matt
