Thanks xmdwpl742 for the detailed answer.
Tommy, I recommend visiting
http://www.cellpack.org/use for a description and interactions on how to view cellPACK models of HIV in Chimera. There is also a link to the autoPACK installation that will allow you to load a model into Cinema 4D, Blender, 3D Studio Max, or Maya. The old versions on the code.google.come/p/autofill site will not work with the latest uPy plugins for cellPACK in the above mentioned 3D software- the most recent recipes are stored as mentioned by xmd on
https://github.com/mesoscope/cellPACK_data and some are directly accessible via the cellPACK/uPy plugin interfaces.
Sorry it is taking us so long to clean this up and document the code and how to use it- I'm looking forward to working on this again soon when I shift positions.
Thanks for your patience!
