Tips:
(1) Step(s):It must be an integer, which means that how many reactions involved at most. Of course, the computing time will be prolonged with its increasment,the maximum number of reactions is limited to 10 for the sake of computation time.
(2) Iterations:Because the retrosynthesis algorithm utilized in ChemHub is iterative, users should enter the iteration-searching times. The retrosynthesis algorithm proceeds until the customized iterations are reached, and each iteration will stop until the predefined steps or the precursor/sink metabolites are reached.
For example: 1,000 times or more. Of course, the computation time will be prolonged with its increasment.
