Identitag is a tool called for tag-to-gene mapping. This tool is based on a relational database which structure can be depicted as three interconnected modules represented in Identitag relational schema. The first one stores virtual tags extracted from transcript sequences belonging to the species considered the second stores experimental tags observed in SAGE experiments, and the third allows the annotation of the transcript sequences used for virtual tag extraction. Identitag therefore connects an observed tag to a virtual tag and to the transcript sequence from which it is derived, and then to its functional annotation when available. For a complete description of Identitag tables see Identitag data dictionary.
