RP2paths
========


**RP2paths** extracts the set of heterologous pathways that lies in a metabolic space file outputted by the `RetroPath2.0 workflow <https://www.myexperiment.org/workflows/4987.html>`_ into individual pathways and enumerate them. This analysis is required to ensure that only pathways fulfilling all the precursor needs are retained for further analysis. This tool takes as input a retrosynthesis network in the CSV file produced by `RetroPath2.0 <https://toolshed.g2.bx.psu.edu/view/tduigou/retropath2/9c8ac9980bd6>`_ , and outputs the enumerated pathways (using `EC numbers <https://www.sciencedirect.com/topics/biochemistry-genetics-and-molecular-biology/enzyme-commission-number>`_ ) as well as the structure of involved chemicals (as SMILES: Simplified Molecular-Input Line-Entry System) in TSV format.


An example of **enumerated pathways** is illustred in the figure below for the production of a target molecule: `Styrene <https://www.sciencedirect.com/topics/chemical-engineering/styrene>`_. **Compounds** are represented by their structures, and **reactions** by their `EC numbers <https://www.sciencedirect.com/topics/biochemistry-genetics-and-molecular-biology/enzyme-commission-number>`_.

Input
-----

Required information:

* **RetroPath2.0 Pathways**\ : Retrosynthesis network CSV file outputted by the RetroPath2 tool which desribes the network linking the targeted compound to the chassis.

Advanced options:

* **Time Out**\ : (integer) Timeout before killing a process (in seconds), default: 30 minutes.

Output
------

* **Enumerated Pathways**\ : Describes all the indiviudal enumerated pathways that produce the compound of interest.
* **Compounds**\ : Describes the structure of all the chemical species involved in all pathways as SMILES (Simplified Molecular-Input Line-Entry System).
