Hi Patrick, Yes it can be done. This question was discussed on the Chimera mailing list in March. http://www.cgl.ucsf.edu/pipermail/chimera-users/2008-March/002447.html Tom Patrick Ladam wrote:

Hello to all,

I have a serie of vectors to draw and update repeatidly. Is it possible to avoid the file open/write/close and makeCommand( 'open myfile.bild' ) process and rather do it in memory within python. In other words, is there a way to interpret bild commands directly in the chimera python module ?

Thanks to all
