HiRes software from Columbia University, New York
High Resolution Spectroscopy (HiRes), is a free Windows software program to provide comprehensive analysis of large NMR spectroscopic data sets. It combines standard spectral processing routines, data correction functions, techniques for reducing information complexity of multi-spectral dataset such as Principal Component Analysis (PCA), and tools for Pattern Recognition, such as Non-Negative Matrix Factorization (NMF), which extracts a set of spectral patterns with direct physical interpretation that can be used for identifying meaningful biochemical effects. These spectral patterns are also correlated with auxiliary information from the samples, such as biological end-points, drug toxicity or disease diagnosis.
