From: Rapper tk: a versatile engine for discrete restraint-based conformational sampling of macromolecules
Rapper tk procedure for RNA sampling. Bootstrap builder assigns the location of a few initial atoms of the first nucleotide by rigid-body transformation from given structure satisfying the positional restraints specified on C5*, C4*, C3* atoms. Chain extension is carried out by RNAbuilder according to the backbone dihedrals sampled by RNAsampler (using the rotamericity described in [4]). RNAbuilder builds the corresponding sugar and base also.
