adSplit

- Find annotations-drive splits

An R package exploring functional annotations to generate biologically motivated splits.

adSplit - Annotation-Driven Splits in Microarray Data

StAM logo 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.
