Retropath2.0 wrapper
====================


Perform retrosynthesis search of possible metabolic routes between a source molecule and a collection of sink molecules. This tool is an implementation of the `KNIME retropath2.0 workflow <https://www.myexperiment.org/workflows/4987.html>`_. It takes for input the minimal (dmin) and maximal (dmax) diameter for the reaction rules and the maximal path length (maxSteps). The tool expects the following files: rules.csv, sink.csv and source.csv and produce a retrosynthesis network as a CSV file providing reactions in the reaction SMILES format and chemicals in both SMILES and InChI formats along with other information like the score for each reaction. Only a single source molecule is processed at this time.

Input
-----

Required:

* **Sink File**\ : (string) Sink file which comprises all compounds that are considered as granted in your system.
* **Source InChI**\ : (string) InChI of compound to produce.
* **Source name**\ : (string) Name of compound to produce.
* **Maximal Pathway length**\ : (integer) The maximal number of metabolic steps (i.e. reactions) for exploring around the target.
* **Rules File**\ : (string) File containing reaction rules which reflect the enzymatic potential of the chassis organism.


Advanced options:

* **TopX**\ : (integer, default: 100) The maximal number of intermediate compounds to use as new starting points for a next iteration of the retrosynthesis algorithm.
* **Minimum rule diameter**\ : (integer, default: 0) Minimum rule diameter of the sphere including the atoms around the reacting center. The higher is the diameter, the more specific are the rules.
* **Maximum rule diameter**\ : (integer, default: 1000) Maximum rule diameter of the sphere including the atoms around the reacting center. The higher is the diameter, the more specific are the rules.
* **Molecular weight of source (Da)**\ : (integer, default: 1000) The molecular weight cutoff (in Da), above which initial source (ie target) and intermediate compounds will be filtered out.
* **Timeout (min)**\ : (integer, default: 60) Maximal time of RetroPath2.0 execution (60 minutes by default)
* **Workflow version**\ : Retropath2.0 Workflow versions, formatted as r{year}{month}{day} (the latest version r20220104 is used by default)

Output
------

* **Reaction Network**\ : CSV file containing retrosynthesis network which provides reactions in the reaction SMILES format and chemicals in both SMILES and InChI formats along with other information like the score for each reaction.
