Clustering tools make massive datasets highly interpretable.
The Functional Annotation Tool is the most widely used component of DAVID. It takes a user-submitted gene list and maps it against a vast array of annotation categories.
Pathway Mapping: DAVID integrates with the Kyoto Encyclopedia of Genes and Genomes (KEGG). It can map your gene list directly onto biological pathway diagrams, highlighting exactly where your genes of interest interact within a metabolic or signaling network. david bioinformatics resources
Groups genes by Molecular Function (MF), Cellular Component (CC), and Biological Process (BP).
Using DAVID is straightforward, even for researchers with no coding or programming experience. Here is the standard analytical workflow: Step 1: Upload Your Gene List Clustering tools make massive datasets highly interpretable
A term may have a highly significant raw P-value but an insignificantly high FDR due to multiple testing. Always rely on the Benjamini-Hochberg or FDR corrected values.

DAVID will automatically analyze your list to determine the species of origin (e.g., Homo sapiens , Mus musculus ). Confirm the correct species to ensure accurate background statistics. Step 3: Choose Your Analytical Tool
The background list defines the "universe" of genes, which directly affects the p-values of your enrichment analysis.
