UNIO
high-throughput and high-output protein structure determination.
The UNIO program enables you to perform automated NMR data analysis for 3D protein structure determination. UNIO represents the result of more than a decade of basic research performed in order to enable accurate, objective and highly automated protein structure determination by NMR.
The UNIO program includes data analysis algorithms for all parts of an NMR structure determination process ranging from backbone and side-chain assignment to NOE assignment and structure calculation. Individual data analysis components have been used in thousands of NMR structure determination projects world-wide.

How to Signup for an Account?
The UNIO web server is free of charge for academic users. You are two steps away from starting your UNIO calculations on the grid:
  • You have to be in possession of a valid GRID certificate that proves that you are allowed to run calculations on the GRID. If you do not yet have one you can find information about obtaining a certificate here
  • Once in possession of a valid GRID certificate you have to register for this web server which will provide you with login credentials and privilages for the server. Go to the signup webform
