Sequence Annotation. An example of our input data and annotation. We see here the 'ancestral' sequence S1, whose genes structure G is given by coding regions in two reading frames GRF1 and GRF2. We apply a partition P to the sequence, where a breakpoint occurs whenever there is a change in gene structure. We annotate this partition with R = 3 different types of region for non-, single and double-coding respectively. Finally we have the descendent sequence S2.
