Cluster coherence for GFC-Single with other gene family inference methods. The bar chart displays coherence at cluster level between GFC-Single and other gene family inference methods. A cluster is termed common cluster if it can be found with exactly the same members in both softwares. A cluster is termed as subset if the first software contains two or more clusters merged together as a single cluster in the second software. Any cluster which is neither common nor subset (or superset) is considered contradictory. As expected, NC-based methods, i.e., NC-Single, NC-Average, NC-Complete, GFC-Average and GFC-Complete have the most number of clusters in common with GFC-Single (shown with blue parts of the bar) and there are no contradictory clusters between these software and GFC-Single. However, other software (HiFiX, MCL, hcluster_sg and SiLiX) have relatively less common clusters with GFC-Single and a few contradictory clusters can also be observed for HiFiX and SiLiX
