Regulatory Sequence Analysis Tools

Welcome to Regulatory Sequence Analysis Tools (RSAT).

This web site provides a series of modular computer programs specifically designed for the detection of regulatory signals in non-coding sequences.

RSAT servers have been up and running since 1997. The project was initiated by Jacques van Helden, and is now pursued by the RSAT team.

This website is free and open to all users.
