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


Perform retrosynthesis search of possible metabolic routes between a source molecule and a collection of sink molecules. Docker implementation of the KNIME retropath2.0 workflow. Takes for input the minimal (dmin) and maximal (dmax) diameter for the reaction rules and the maximal path length (maxSteps). The docker mounts a local folder and expects the following files: rules.csv, sink.csv and source.csv. We only support a single source molecule at this time.

Input
-----

Required:

* **-sinkfile**\ : (string) Path to the sink file
* **-sourcefile**\ : (string) Path to the source file
* **-max_steps**\ : (integer) Maximal number of steps
* **-rulesfile**\ : (string) Path to the rules file
* **-rulesfile_format**\ : (string) Valid Options: tar, csv. Format of the rules file

The InChI source DB entries are obtained by the following command:

`cat chem_prop.tsv | awk -F'\\t' '{print "\\t\\t\\t\\t\\t<option value=\\""$6"\\"\\>" "["$1"]\\t " $2 "</option>"}' | sed 's/\\&/\\&amp;/g'`

where `chem_prop.tsv` has been downloaded on MetaNetX.

Advanced options:

* **-topx**\ : (integer, default: 100) For each iteration, number of rules
* **-dmin**\ : (integer, default: 0)
* **-dmax**\ : (integer, default: 1000)
* **-mwmax_source**\ : (integer, default: 1000)
* **-mwmax_cof**\ : (integer, default: 1000)
* **-timeout**\ : (integer, default: 30) Timeout in minutes

Output
------

* **-scope_csv**\ : (string) Path to the output scope csv file
