Constructor & Destructor Documentation

Dihedral ( const AtomImplPtr atom1,
const AtomImplPtr atom2,
const AtomImplPtr atom3,
const AtomImplPtr atom4 
)

construct new dihedral as defined by the four consecutive atoms atom1 to atom4

Dihedral ( const AtomImplList atoms  ) 

construct new dihedral as defined by the four consecutive atoms stored in atoms

void SetAngleICS ( Real  angle,
bool  update_other 
)

set dihedral angle. Requires an intact internal coordinate system.

Parameters:
angle new angle in radians
update_other If true, connectors of atom3 are updated accordingly, otherwise they will be left untouched
