Graphical design of chemical discovery processes

A computer program product on a computer-readable medium for generating a library design for a set of experiments, comprising instructions operable to cause a programmable processor to:

• define a library array representing an arrangement of experiments in the set of experiments, the library array including electronic data defining a plurality of elements, each of the plurality of elements representing a potential location for an experiment in the set of experiments;
• define a plurality of sources, each of the plurality of sources including electronic data representing a material or condition that can be used in the set of experiments;
• receive user input defining a plurality of maps representing the application of sources to elements of the library array, each of the plurality of maps including electronic data identifying one or more library elements and defining an amount of a corresponding source to be applied to the identified library elements, the plurality of maps being ordered to define a mapping sequence;
• and
• generate a library design including electronic data representing the library array, the sources, the maps and the mapping sequence, the library design specifying for each of a plurality of library elements amounts of one or more sources to be applied to the corresponding library element, the amounts being defined at least in part by the order of maps in the mapping sequence.
