Chemical descriptors calculation


According Todeschini and Consonni chemical descriptor is "The molecular descriptor is the final result of a logic and mathematical procedure which transforms chemical information encoded within a symbolic representation of a molecule into a useful number or the result of some standardized experiment". A key steps in classical quantitative structure-activity/property relationship (QSAR/QSPR) modeling is the encoding of a chemical compound into a vector of numerical descriptors.
