Perhaps you should try some spelling variations:
programming postprocessing » programming preprocessing, programming processings, programming preprocessor
optimization microarray » hybridization microarray, optimization microchip, identification microarray
postprocessing problem » processing problems, postprocessing system, postprocessing procedure
activation microarray » annotation microarray, applications microarray, generation microarray
