SPELL is an online search engine for large compendia of gene expression microarray data. The current SPELL website is based on a collection of ~2400 S. cerevisiae microarray conditions. The underlying algorithm is a query-driven search utilizing a novel application of SVD for signal balancing and using the Fisher Z-transform for improved comparability between datasets.
