__init__(self, msys_model, cms_model, aids, ref_pos, fit_aids=None, fit_ref_pos=None, in_place=False)
See L{PosAlign} for parameters.
 
_precalc(self, calc)
Reusable intermediate data saved in calc: We use the _center function, and create one copy of the trajectory frame and one copy of the full-system CT.
 
_postcalc(self, calc, _, fr)

__init__(self, msys_model, cms_model, aids, ref_pos, fit_aids=None, fit_ref_pos=None, in_place=False)
(Constructor)

 

See L{PosAlign} for parameters.

@param     ref_pos: positions of reference conformer structure
@type      ref_pos: Nx3 C{numpy.ndarray}
@param    in_place: if True, calculate RMSD without applying
                    transformations on C{ref_pos}

Typically, C{aids} and C{fit_aids} come from a common source whereas
C{ref_pos} and C{fit_ref_pos} come from another common source.

Parameters:
  • fit_ref_pos - positions of reference conformer structure for translation/rotation calculation
Overrides: object.__init__

_precalc(self, calc)

 

Reusable intermediate data saved in calc: We use the _center function, and create one copy of the trajectory frame and one copy of the full-system CT. In both, the solute atoms are centered.
