CYANA Function: lda
lda(integer) = integer
Number of the last atom that is affected by a change of dihedral angle n.
For the dihedral angle with the given index this function returns the index of the index of the last atom that is affected by a rotation of this dihedral angle. This function returns na+1, i.e. the number of atoms plus 1, for backbone dihedral angles and for fixed dihedral angles.
Optionally, the integer dihedral angle index can be replaced by a string consisting of the dihedral angle name and the residue number, separated by a blank or a period, ..
