`getLeontisList`: Get list of representative/non-redundant RNA structures organized in Equivalence Classes (source: Leontis & Zirbel, 2012).
`getRNAList`: Get list of representative/non-redundant RNA structures organized in Equivalence Classes (source: Leontis & Zirbel, 2012).
`getAltRepres`: Apply filters (e.g. just protein-RNA structures) to select other representants from the members of each class.
`represAsDataFrame`: From the output of getLeontisList or getAltRepres, generate a data.frame in which each row corresponds to a RNA chain, rather than an Equivalence Class.
`represAsDataFrame`: From the output of getRNAList or getAltRepres, generate a data.frame in which each row corresponds to a RNA chain, rather than an Equivalence Class.
`pipeNucData`: From a list of RNA structures/chains computes and returns structural data at the level of the nucleotide.
