Nearest neighbor parameters for RNA folding are used widely in software packages, but no current published source exists to provide the parameters and a tutorial for their use. This database serves this function for the community and is intended to grow as the parameters are refined. The site will also be used to provide a historical record of parameter sets as they are subsequently refined.
