The "filtering" directory contains scripts and data for quality filtering of non-redundant DNA and RNA residues forming the "PDB NA Reference Set".

The "naval" directory contains a C++ re-implementation of the python-based annotation code (https://github.com/mkowiel/nucleic-acid-validation.git).
The C++ program depends on the "libLLKA" library used at the https://dnatco.datmos.org web service. The source code is available from https://github.com/cernylab/libLLKA.git repository.

The "prosco" directory contains the R script and auxiliary shell scripts for (re)calculation of the *_prosco.json files. It uses the "naval" annotated csv files from "pdb_na_reference_set.zip" as the input.
