From: DIRECT: RNA contact predictions by integrating structural patterns
The number of correctly predicted contacts according to the conservation grades of the two nucleotides involved in the contact for all tested riboswitch RNAs. The contacts are divided into variable type (both nucleotides with conservation-grade 1–3), conserved type (both nucleotides with conservation-grade 7–9), and others, respectively. a, b, c, d, e, and f The performance of DIRECT (yellow) in comparison to DCA (blue) is considerably better for the variable contacts and only slightly improved for the conserved contacts
