Figure 1From: Strategies for measuring evolutionary conservation of RNA secondary structuresRelation between the average pairwise sequence identity and the normalized Shannon entropy. The Shannon entropy is used as measure for information content contained in an alignment throughout this paper. It depends on the average pairwise identity and the number of sequences in the alignment. The lines shown are regression lines for the nearly exact linear relationship (R2 > 0.99) between Shannon Entropy and the mean pairwise identity.Back to article page
