     - Hierarchical folders of the training/testing sets containing single-chain [PDBx/mmCIF](https://en.wikipedia.org/wiki/Macromolecular_Crystallographic_Information_File) files 
     - Most convenient for getting started with training and testing using RNA3DB
     - This format is currently experimental. If you find any problems, please [submit an issue](https://github.com/marcellszi/rna3db/issues).
