NMRProcFlow: a graphical and interactive tool dedicated to 1D spectra processing for NMR-based metabolomics

Concerning NMR-based metabolomics, 1D spectra processing often requires an expert eye for disentangling the intertwined peaks. The objective of NMRProcFlow is to assist the expert in this task in the best way without requirement of programming skills. NMRProcFlow was developed to be a graphical and interactive 1D NMR (1H & 13C) spectra processing tool. NMRProcFlow ( http://nmrprocflow.org ), dedicated to metabolic fingerprinting and targeted metabolomics, covers all spectra processing steps including baseline correction, chemical shift calibration and alignment. Biologists and NMR spectroscopists can easily interact and develop synergies by visualizing the NMR spectra along with their corresponding experimental-factor levels, thus setting a bridge between experimental design and subsequent statistical analyses.
