Welcome to the ARIAweb service

ARIA (Ambiguous Restraints for Iterative Assignment) is a software for automated NOE assignment and NMR structure calculation. It speeds up and automatizes the assignment process through the use of an iterative structure calculation scheme. Additionally, a refinement in explicit water improves the quality of the calculated structures, validation tests help spectroscopists to judge the quality of the final structures, and the support of the CCPN data model simplifies the exchange of information with other NMR software packages.
