Database for Annotation, Visualization, and Integrated Discovery (DAVID)

The is a free, high-throughput bioinformatics resource designed to extract biological meaning from large gene or protein lists. It is widely used for functional annotation enrichment analysis, helping researchers identify biological themes and pathways associated with their data. Core Analysis Tools

• Category: (e.g., GOTERM_BP_DIRECT)
• Term: (e.g., "Innate Immune Response")
• Count: (Number of your genes in this term)
• P-Value: (EASE score, a modified Fisher Exact p-value)
• Benjamini: (False Discovery Rate correction for multiple testing)

2. The Gene Functional Classification Tool

DAVID

In the post-genomic era, translating long lists of genes into biological meaning is a major challenge. Enter — one of the most widely used, freely accessible bioinformatics resources for functional annotation and enrichment analysis. david bioinformatics resources

Step 2: Define Background

You must specify the "background" or "universe." For most experiments, the default is the whole genome of your selected species (e.g., Homo sapiens ). However, for custom arrays or targeted sequencing, you can upload a custom background list to avoid false positives. Category: (e

• Accepted ID types: Entrez Gene ID, Official gene symbol, Ensembl, UniProt, RefSeq, and others — always confirm chosen ID type on upload.
• Species support: many model organisms and human; select species carefully to avoid incorrect mapping.
• Outputs: enrichment tables (terms, gene counts, percentage, p-value, Benjamini/FDR), clusters with enrichment scores, annotation tables mapping genes to terms, and downloadable files.
