sci-chemistry jlec@gentoo.org Suitename is a new C program that supports the ROC RNA Ontology Consortium consensus RNA backbone nomenclature and conformer-list development (see our RNA backbone rotamer section. From dihedral-angle input for a specific RNA structure (usually from Dangle), Suitename categorizes the RNA backbone geometry of each suite (the sugar-to-sugar version of a residue) either as an outlier ("!!") or as belonging to one of the 53 defined conformer bins. The output is either a one-line-per-suite report, or a linear conformer string (as shown below the image here) in one of several variant formats. Suitename is built into MolProbity, producing entries in the multi-criterion chart for an RNA model and also a suitestring file. The Suitename code is made available here for bulk or individual command-line use.
