The use of high-throughput, information-rich technologies such as microarrays, high-content screening (HCS) and next-generation sequencing (NGS) has become increasingly widespread in pharmaceutical research and development. Compared to single-readout assays, these methods can produce a more comprehensive look at the biological activities of screened treatments. However, interpreting multidimensional readouts can be a challenge. Univariate statistics such as t-tests and Z-factors cannot easily be applied to multidimensional data, requiring the development of other methods to answer common screening questions like “Is treatment X active in this assay?”, “Is treatment X a hit?”, and “Is treatment X different from treatment Y?” We have developed a simple, straightforward metric, the multidimensional perturbation value (mp-value), which can be used to answer these questions. The mp-value has successfully distinguished active from inactive treatments using data from a variety of platforms. We believe the mp-value has great potential to simplify the analysis of multidimensional data while taking full advantage of its richness.
