Differentiating exact and inexact matches. A partial view of the output of the CorBank program obtained when comparing the two versions of the genome of the archeon Pyrococcus horikoshii OT3 is detailed in several tables. Table A recapitulates the respective database information about this species and its computed label. Table B shows a summary of the data obtained using CorBank to find what is either common to both databases or specific of each one. Table C illustrates a few instances of exact matches. Table D exemplifies a few inexact matches with detailed configuration of the difference in the structural annotations of each copy of the same gene. The definitions of these inexact configurations are given in the Additional file 1.
