Figure 1From: 4SALE – A tool for synchronous RNA sequence and secondary structure alignment and editingITS2 sequence and secondary structure ratematrix. This figure shows the estimated sequence/secondary structure substitution rates (*105). Diagonal entries are by definition the negative sum of all row entries. Note, high rates depict frequent substitutions, and vice versa small rates depict rare substitutions, e.g., within a secondary structure Cs an Us are often replaced by each other.Back to article page
