VeRNAl: Mining RNA Structures for Fuzzy Base Pairing Network Motifs

2 code implementations1 Sep 2020 Carlos Oliver, Vincent Mallet, Pericles Philippopoulos, William L. Hamilton, Jerome Waldispuhl

State of the art methods solve special cases of the motif problem by constraining the structural variability in occurrences of a motif, and narrowing the substructure search space.
