Some informal examples explanations

The key concept to understand when working with FALDO is that positions are like coordinates on a map.

I think I can explain it best with an example. Take UniProt P13744 and PDB 2E9Q

See the magnesium binding annotation on the UniProt sequence position 408. That binding is on position 408 on the UniProt sequence, but its on position 22 of the pdb/primary sequence.

   example:magenesiumFeature a up:Annotation ;
     faldo:location example:magnesiumPositionOnUniProt , 
                     example:magnesiumPositionOnPDB .

   example:magnesiumPositionOnUniProt a faldo:ExactPosition ;
     faldo:position 408 ;
     faldo:reference uniprot:P13744 .

   example:magnesiumPositionOnPDB a faldo:ExactPosition ;
     faldo:position 386 ; #Shift by 22
     faldo:reference pdb: 2e9q/primary_sequence .

In this case the same thing can be found on two “maps” just like Tokyo can be found at BING maps as well as Google Maps.
