DAVID Gene Functional classification
The Functional Classification Tool generates a gene-to-gene similarity matrix based shared functional annotation using over 75,000 terms from 14 functional annotation sources. The novel clustering algorithms classifies highly related genes into functionally related groups.

DAVID Gene ID Conversion Tool (DGCT)
If a significant portion (>20%) of input gene IDs fail to bemapped to an internal DAVID ID, a specially designed module, the DAVID Gene ID Conversion Tool, will start up to help map such IDs.
DAVID Gene Name Batch Viewer
1. The gene name batch viewer is able to quickly attach meaning to a list of gene IDs by rapidly translating them into their corresponding gene names.
Identify enriched biological themes, particularly GO terms Discover enriched functional-related gene groups Cluster redundant annotation terms Visualize genes on BioCarta & KEGG pathway maps Display related many-genes-to-many-terms on 2-D view. Search for other functionally related genes not in the list List interacting proteins Explore gene names in batch Link gene-disease associations Highlight protein functional domains and motifs Redirect to related literatures Convert gene identifiers from one type to another.
2. before proceeding to analysis with other more comprehensive analytic tools, investigators can quickly glance at the gene names to further gain insight abstions.

DAVID Analytic Modules
Any given gene is associating with a set of annotationterms. If genes share similar set of those terms, they are most likely involved in similar biologicalmechanisms. The algorithm adopts kappa statistics to quantitatively measure the degree of the agreement how genes share the similar annotation terms. Kappa result ranges from 0 to 1. The higher the value of Kappa, the stronger the agreement. Kappa more than 0.7 typically indicates that agreement of two genes are strong. Kappa values greater
