Comparison of gene/gene pair overlap on matching pathways. Image comparing the percentage of gene and gene pair overlap between matching pathways obtained from the LCS algorithm (in blue) and that of the gene overlap algorithm (in pink). The pink marks refer to pathways which are unable to be paired by the LCS algorithm. The x-axis depicts the gene overlap percentage and the y-axis the gene pair overlap percentage. The image shows that pathways matched by the LCS algorithm consistently have a higher gene pair overlap percentage.
