Beyond the capacity to give an overall measure and view of the central genome similarity with a set of compared genomes, the partition offers the possibility to determine which functional sequence elements are shared or genome specific (which may require several comparisons). If provided with the annotations of the central genome, qod computes the inclusion/overlap of annotations with each partition segment and gathers its related annotations in those two categories (included/overlapping). Moreover, it extracts from the segment possible alignments the sub-alignments corresponding to annotated features and displays them on the gui.
