am looking for an analysis tool in Chimera  that would write out - let's say a matrix for translation/rotation of a pdb-file in respect to another one.

Usage:  would like to align chain A and chain B present in a pdb-file and want to know which translation/rotation matrix has to be applied in order to convert  the non-aligned pdb-coordinates of chain B to the 'new" aligned pdb-coordinates.

Thanx for your help,

-Thomas
