DAVID-对芯片数据的生物学分析有价值的database

芯片数据的生物学分析是大家都感到头疼的问题，对着大量差异表达的基因无从下手，不知这些基因的功能，不知参与了哪些pathway，DAVID可在这些方面可以提供许多有价值的信息。

These tools were developed by the Laboratory of Immunopathogenesis and Bioinformatics at SAIC-Frederick, Inc. for the National Institute of Allergy and Infectious Diseases of the National Institutes of Health. DAVID and EASE provide integrated solutions for the annotation and analysis of genome-scale datasets derived from high-throughput technologies such as microarray and proteomic platforms.

最主要的功能是对基因进行Annotation（阐述基本的功能），GO分类，KEGG中参与的信号途径。下面分别阐述一下。
