FMM is a method of generating K antigens using virtual bond cartesian coordinate transfer matrices. Here, the user is given the flexibility to choose desired inter-residue glycosidic torsion angles.

NOTE :

- Intra-residue glycosidic torsion angles are fixed.

- Some pairs of torsion angles may lead to steric hindrance.

- Definition of phi, psi flows in the decremental order of main chain residue number (View documentation for more details).

- Note that the models generated here have identical torsion angles for the repeating unit and may not represent the global minima of the molecule; these models are well-suited as good starting points for modeling studies
