I have blogged about two Molecular Chemometrics principles so far: McPrinciple #1: access to data McPrinciple #2: be clear in what you mean Peter’s post #solo10: Green Chain Reaction; where to store the data? DSR? IR? BioTorrent, OKF or ??? gives me enough basis to write up a third principle: Molecular Chemometrics Principles #3 : We make scientific progress if we build on past achievements. Sounds logical, right?
