Table S2. Clusters involved with indel or mutation events.

The 1st column is the Cluster ID, which is consistent with the ID in Table S1. The 2nd column is the cluster conservation of current cluster.

The 3rd column is the variation position, which counts according to the alignment result of protein sequences in this cluster. For indel events, the position is an integer. For synonymous mutation and non synonymous mutation, the position is a floating number, in which the integer part marks the position of the amino acid in the alignment result of protein sequences, while the decimal part mark the position of codon.
