Re: [PyMOL] reset TTT matrix to identity

[Philip Kiser]

Hi Jarrett,
That command seems to just move the object back to its original position
instead of resetting the matrix values with the object kept in its new
position.
Regards,
Philip

Ah apologies,

I am not sure of the most efficient way to do it, but one could store the
TTT matrix, reset the matrix, and transform the object as a selection so
that the positions themselves are changed and not the object transform.

Something like
PyMOL>mat = cmd.get_object_matrix('1obyA')
PyMOL>cmd.matrix_reset('1obyA')
PyMOL>cmd.transform_selection('1obyA', mat)


comes to mind.

Hi Philip,

Have you tried the `matrix_reset` command instead?
