Parallel analyses of thousands of molecules based on hybridization to nucleotides are carried out on microarrays. The large amount of data generated from scanning such arrays needs bioinformatic handling in the form of noise filtering, calibration and normalization to be ready for experimental comparison with other arrays. This may provide insight into regulatory pathways and lead to reclassification of diseases.
