adSplit - Annotation-Driven Splits in Microarray Data

adSplit is an R/Bioconductor Package which implements annotation-driven splitting of microarray data into two classes. Functional annotations of genes are used to restrict expression matrices linked to particular annotations. Splits are then computed using 2-means clustering The biological terms used are derived from the Gene Ontology, as well as the KEGG database of pathways.
