My preference is to use a 1- based system. It's more natural for
biologists and seems to be more popular when numbering residues. PDB ATOM
records typically start at 1 and BLAST results are reported with the first
residue as 1.
However, it's less clear how the end index should behave. I personally
prefer that the end is exclusive.

I seem to fall in OMG's camp.
