Hi, 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 ------------------------------------------------------------------------ ------- Thomas C. Marlovits, PhD, M.A.S.
