The current release of DARTS reflects the structural repertoire of RNA
based on all the 1333 solved RNA structures that were available in the
PDB in March
2007. DARTS provides a set of 244 structures that represents the whole
data (maximum 90% 3D structural or sequential identity). Each of the
remaining structures is assigned to one representative structure as
either a highly-identical structure or a highly-identical fragment. In
addition, DARTS provides a hierarchical classification of all the 1333
RNA structures into 94 clusters. The description of each cluster is a
dendrogram of its representatives, where each representative is
assigned with two sets of its highly-identical structures and
fragments.
The hierarchical clustering method used to construct DARTS is
fully automated and is mainly based on spatial similarity, as
determined by ARTS.
