[Chimera-users] superimpose models from inside a python script and access the transformation matrix

[Eric Pettersen]

Hi Maik,
	I don't know of a non-cumbersome way.  If you are adept at Python programming, the function that the match command calls is Midas.match(), defined in that module's __init__.py file, and you could lift the code that does the match and computes the matrix from there.  The Midas module is found in <your Chimera installation>/share/Midas on Windows/Linux and in Chimera.app/Contents/Resources/share/Midas on Mac.
