This tool performs retrosynthesis search for possible metabolic routes between a source molecule and a collection of sink molecules. It takes as input, files from RetroRules, source and sink compounds (can be generated as explained in SynBioCAD Utilities), and the maximal pathway length (i.e; the number of steps). Only a single source molecule is processed at this time. Using Advanced Options, you can define the maximum number of compounds to keep for a next iteration (TopX), the minimal (dmin) ...
