From: SSS-test: a novel test for detecting positive selection on RNA secondary structure
Local lncRNA structure SIX3-AS1sub11: a human, b pan, c orangutan, d gorilla and e macaque. Only the human structure obtained an SSS-score indicating positive selection with s=12.2 while the other species have strong negative selection scores (s=0.0). Structures are represented by their minimum free energy. Base colors are assigned according to their pairing frequency in the structure’s ensemble. Shades of red occur in ≥90% of the ensemble, shades of green/yellow denote increasing probabilities from ≥50%. For unpaired bases, shades of red denote increasing unpairedness
