<p>This workflow reads in a starting SMILES fragment or molecule from one column and a list of small SMILES patterns from another column. The workflow will replace any CH bond on the starting molecule or fragment SMILES string with all possible CH bonds of the list of small SMILES patterns to form a new C-C bond for example. Also replaces all O-H and N-H bonds. The result is a library of close analogs of a starting molecule or fragment substituted at all positions. Useful for hit optimization with docking for example. An example fragment and replacement file is preloaded.</p>
