Dear chimeras users and developers,

I would like to translate and rotate a model according to the rotation and translation matrix given by a fitmap. More precisely :  I fit model #2 in map #1 and save the corresponding translation and rotation matrix with the save command. Then, I want to turn and move a model #3 so that it has the same position and rotation as model #2 (each correspond to the same pdb file). However, I want to do this automatically, so I need to do it from the matrix that is saved in a .positions file, and not from the (axis, axis point, rotation angle and shift along axis) values given by fitmap, but from the Matrix rotation and translation values. So far,

- I compute the axis of rotation and the angle from the rotation matrix given by fitmap models #2 inMap #1

- I turn #3 around this axis and angle, in coordinateSystems #1

- I apply the translation also measured by fitmap models #2 inMap #1 to #3 (with three calls of the move command, for each axis x,y,z)

Maybe this has to do with the rotation center that is used in fitMap, but it cannot be saved in a .positions file, and I don't know how to recover it from the matrix rotation and translation given by fitmap. Do you have any idea of what I'm doing wrong, or how I could place model #3 at the same exact position as model #2 from the .positions file of model #2, and by moving and rotating model #3 ? (What I want to do then is re-apply this same transformation to build a chain of the same protein)

Thanks,

Lar
