Hi Paweł - Honestly, if you prefer to use matrices, I'd say just go ahead and use get_object_matrix; I doubt it's going away any time soon. You may want to use this in combination with transform_selection<http://www.pymolwiki.org/index.php/Transform_selection>.
Also maybe check out Christoph Gohlke's transformations.py script<http://www.pymolwiki.org/index.php/Transformations>. It offers several tools for manipulating quaternions, matrices, and angle/axis operations. I think there's also a newer version on his website, which is linked from the wiki page.

I've found that it is easier for me to modify a TTT matrix rather than using translate/rotate functions. Documentation says [http://www.pymolwiki.org/index.php/Get_object_matrix] get_object_matrix is unsupported operation. So how to get/set TTT? The problem is, that I get (from external source) position in quaternions and now I need to make my CGO position equal to those quaternion. How can I make it work?
