Users can paste a list of gene identifiers. DAVID supports a massive variety of IDs:
Using DAVID is a straightforward process accessible through a web-based interface. david bioinformatics resources
The most conservative method, controlling the family-wise error rate. Users can paste a list of gene identifiers
Choose "Functional Annotation Chart" or "Functional Annotation Table" to start the analysis. which looks for enriched terms
Experimental data often comes from different platforms (e.g., microarrays, RNA-Seq), leading to various ID types (Gene Symbol, Entrez ID, Ensembl ID). The DAVID Identifier Converter maps these varied identifiers into a standardized "DAVID Gene" ID, facilitating seamless integration. 4. How to Use DAVID: A Typical Workflow
Unlike the annotation tool, which looks for enriched terms , this tool clusters the genes themselves. It uses a novel agglomeration algorithm to group genes based on the co-occurrence of functional annotations. This helps identify "biological modules"—groups of genes that work together—even if those genes are not yet well-characterized in traditional pathways. Key Features and Recent Updates
