RRulesParser
============

Retrieve the reaction rules from `RetroRules <https://retrorules.org/>`_ extracted from public databases and expressed in the community-standard SMARTS (SMILES arbitrary target specification) format, augmented by a rule representation at different levels of specificity (the atomic environment around the reaction center).

The generated output is a file containing reaction rules which are generic descriptions of chemical reactions that can be used in retrosynthesis workflows (e.g. `Retrosynthesis KNIME Workflow <https://www.myexperiment.org/workflows/4987/versions/2.html>`_) in order to enumerate all possible biosynthetic routes connecting a target molecule to its precursors.

Input
-----

* **Rule Type**: (string) Return the rules that are in reverse, forward, both direction or from an input user file
* **rules-file**: (string) Filename of reaction rules provided in csv or tsv format.
* **input_format**: (string) input file format (csv: default, tsv)
* **diameters**: (integer list) diameter of the sphere including the atoms around the reacting center (default is including all values: 2,4,6,8,10,12,14,16). The higher is the diameter, the more specific are the rules

Ouput
-----

* **out_rules**: (string): file containing the parsed reactions rules (default=csv). It will be zipped if *Compress output* is set to yes.
