Assignment Software

Auto Assign

AutoAssign is a constraint-based expert system for automating the analysis of backbone resonance assignments using triple resonance NMR spectra of small proteins. Go to the service >>


MARS is a program for robust automatic backbone assignment of 13C/15N labeled proteins. MARS simultaneously optimizes the local and global quality of assignment to minimize propagation of initial assignment errors and to extract reliable assignments. It can be applied independent of the assignment complexity, it does not require tight thresholds for establishing sequential connectivity or detailed adjustment of these thresholds, it can work with a wide variety of NMR experiments and it is robust against missing chemical shift information. Go to the service >>


The UNIO program enables you to perform automated NMR data analysis for 3D protein structure determination. It includes data analysis algorithms for all parts of an NMR structure determination process ranging from backbone and side-chain assignment to automated NOE assignment and structure calculation.
