There are currently three types of process. First it is possible to perform a series of reaction transforms on a single set of molecules (e.g. remove protecting groups). Alternatively one can perform bimolecular reactions (e.g. amide formation) with prior manipulation of the individual components (e.g. deprotection) and post-coupling modification. Thirdly it is possible to enumerate a library involving many components in a "flow" scheme
To use these options you need to have created your sets of monomers and then deposited them
