A software tool for the alignment of large GC-MS-based metabolite profiling experiments into statistically accessible data matrices. The matrix generation is directed by co-analysis of retention index (RI) marker substances within each chromatogram and the simultaneous in-parallel analysis of mixtures of reference compounds is recommended. In addition, we offer automated extraction of quantitative data from predefined mass fragments, time groups of mass fragments or clusters of intensity-correlated mass fragments. TagFinder is freely available for academic use.
Allows metabolome analysis of large-scale multiple reaction monitoring (MRM) assays. MRMPROBS is a universal program for targeted metabolomics using multiple reaction monitoring (MRM)- or selected reaction monitoring (SRM), as well as SCAN and data independent tandem mass spectrometry (MS/MS) acquisition (DIA) data. The software was developed for metabolomics but can also be applied to lipidomics and proteomics studies.
Assists users in analyzing unsupervised data mining on gas chromatography-mass spectrometry data. MSeasy is an alternative approach for gas chromatography-mass spectrometry (GC-MS) data processing, insensitive to shift in retention time. It works directly on the raw mass spectra (MS) rather than on extensively corrected chromatograms. This method accelerates the data processing and supports interpretation of complex GC-MS datasets by extracting human-understandable structure and supplying quality control criteria.
A web-based tool that objectively quantifies every metabolite peak detected in a set of samples and aligns peaks across multiple samples to enable quantitative comparison of each metabolite between samples. The analysis incorporates quantification of multiple peaks/ions that have different chromatographic retention times but are detected within a single SRM transition.
Provides functions to schedule the high-throughput acquisition of targeted tandem mass spectrometry data. MetShot performs (1) preparation and export of liquid chromatography coupled to tandem mass spectrometry (LC–MS/MS) methods, followed by data acquisition; and (2) processing of the resulting LC–MS/MS raw data and extraction of tandem mass spectra into compound spectra.
An open source tool which is a flexible and accurate method for pre-processing very large numbers of GC-MS samples within hours. A novel strategy was developed to iteratively correct and update retention time indices for searching and identifying metabolites. TargetSearch includes a graphical user interface to allow easy use by those unfamiliar with R. It allows fast and accurate data pre-processing for GC-MS experiments and overcomes the sample number limitations and manual curation requirements of existing software.
An R package that allows the selection of the optimal set of fragments and retention time windows for target analytes in GC-SIM-MS based analysis. SIMAT provides guidance in choosing fragments for a list of targets. This is accomplished through an optimization algorithm that has the capability to select the most appropriate fragments from overlapping chromatographic peaks based on a pre-specified library of background analytes. The tool also allows visualization of the total ion chromatograms (TIC) of runs and extracted ion chromatograms (EIC) of analytes of interest. Moreover, retention index (RI) calibration can be performed and raw GC-SIM-MS data can be imported in netCDF or NIST mass spectral library (MSL) formats.
Permits researchers to analyze the mass spectrometry data for: peak detection, peak alignment, peak normalization, biomarker discovery, baseline correction, and denoising. msPeak consists of a peak detection algorithm that utilizes a normal-exponential-Bernoulli (NEB) model and mixture probability models. This program is able to perform simultaneous baseline correction and denoising, followed by finding the potential peak regions. Moreover, the peak picking and area calculations are carried out by fitting experimental data.
Aims to formalize the analysis of gas chromatography-mass spectrometry (GC/MS) data. PYQUAN uses the AMDIS data to align the individual samples against the personal retention time (RT) library. It offers the possibility to backfill expected peaks in samples where AMDIS did not recognize those peaks. Moreover, this program utilizes AMDIS for producing for each peak a list of all possible identifications, based on a personally managed mass spectra library.
