Peak alignment software tools | NMR-based metabolomics data analysis
Spectral alignment is one of the main processing steps in metabolomic studies involving multiple samples. When analyzing multiple spectra, the position of the peaks corresponding to the same metabolic feature may be affected by non-linear shifts. In NMR-based studies, these shifts are observed in the ppm axis and are usually introduced by differences in the chemical environment of the sample like ionic strength, pH, or protein content.
A tool for the alignment of spectral datasets. The icoshift tool for Matlab is an open source program specifically designed for solving signal alignment problems in metabonomic NMR data analysis, but it can also properly deal with other spectra-like datasets (e.g. data from other spectroscopic methods or chromatographic data). The icoshift algorithm is based on COrrelation SHIFTing of spectral Intervals and employs an FFT engine that aligns all spectra simultaneously.
Assists users nuclear magnetic resonance (NMR)-based metabonomics or metabolomics spectral processing and data analysis. Automics is a highly integrated platform that was developed to aid researchers for processing high dimensional NMR spectroscopic data. In addition, features such as data organization, data preprocessing and a wide range of data investigation techniques for multivariate data analysis, classification and regression have been implemented.
An interactive 1D NMR spectra processing tool dedicated to metabolomics. The NMRProcFlow open source software provides a complete set of tools for processing and visualization of 1D NMR data, the whole within an interactive interface based on a spectra visualization.
Provides a rapid workflow from raw Nuclear Magnetic Resonance (NMR) data to patent and publication quality output. dataChord Spectrum Analyst is a graphic application for small molecule NMR Analysis that provides a variety of analytical tools for interpreting NMR Spectra. It can work in a client server mode with the spectrum server maintaining an archive of annotated raw data. This module can compare multiple spectra with each other and generates reports that include a variety of information, including molecular structures.
