Diagram illustrating the computation of the maximum number of unique homologous matches. We counted the homologous matches between 3 neighboring genes (shown as filled arrows with corresponding gene orientations) on each side of the two genes of interest (GOI, shown as two black boxes). Homology between neighboring genes (shown as line between genes) is defined as Blastp E-value < 1e-5. The homologous matches do not need to be between the genes with the same orientations (1) or on the same strand (2). Also they do not need to be co-linear (3). When there are many-to-many homologous matches, we choose the maximum unique matches (4). The number of maximum unique homologous matches in this case is 5.
