Figure 4
Example of a link. This example describes the α1–4 pyranose link. See Fig. 2[link](b) for a graphical representation of this link. The first (general) category (_chem_link) describes the name, the link identification code and the scope of this link. It also contains pointers to the modifications the monomers should undergo before the link can be applied. This link requires that the monomers belong to the `pyranose' group and that the first and second monomers undergo DEL-HO4 and DEL-O1 modifications, respectively. The description for both these modification need to be available before the link can be applied. Other categories give the list of bonds (_chem_link_bond), bond angles (_chem_link_angle), torsion angles (_chem_link_tor), chiralities (_chem_link_chir) etc. with their `ideal' values. Atom names in the link description are always given together with the monomer numbers they belong to.
