RNA Structure Atlas

- provides annotations of base-pairing, -stacking, and -backbone interactions computed by FR3D

- extracts internal, hairpin and 3-way junction loops and annotates them with motifs from the RNA 3D Motif Atlas

- organizes redundant structures into representative sets of equivalence classes

We are upgrading BGSU RNA Site to include new RNA 3D structures distributed in mmCIF format. Follow us on Twitter to hear when the updated version becomes available.
