A total solution to deal with not only data dependent MS/MS but also data independent MS/MS experiments for metabolomics and lipidomics. Its feature is 1) implementing de-convolution method for data independent MS/MS 2) using unified criteria for peak identification 3) supporting all data processing step from raw data import to statistical analysis 4) user-friendly graphic user interface. MS-DIAL deals with data independent acquisition MS/MS data (ex. SWATH) by means of two step algorithms (peak spotting and MS2Dec) for spectral deconvolution. Also, it supports compound identification, peak alignment, and principal component analysis on the graphical user interface. The spectrum information is outputted by MassBank, NIST, and Mascot formats. And the organized data matrix (sample vs metabolite) is exported as tab delimited text file.
Finds and integrates peaks in a mass spectrum, matches the peaks with a user-supplied list of expected lipids, corrects for overlap in their isotopic patterns, and quantifies the identified lipid species according to internal standards.
Helps to discover new lipid molecular species. LipidFinder is a computational workflow which searches three independent online databases to obtain putative identification of lipids, and assigns them to a class based on the LIPID MAPS system. The software quickly distinguishes and quantifies lipid-like features from contaminants, adducts and noise in high resolution liquid chromatography/mass spectrometry (LC/MS) datasets that have been pre-aligned using SIEVE (ThermoFisher) or XCMS.
A high throughput lipid identification tool. SimLipid® accepts experimental MS and MS/MS data, enables lipids profiling by searching precursors against the known lipid structures and elucidates an unknown structure by matching experimental product ions against theoretical fragments of lipids from the database. It also supports LC-MS and LC-MS/ MS high throughput data processing methods providing a platform for further qualitative and quantitative data analysis.
Preprocesses liquid- or gas-chromatography mass spectrometry (LCMS/GCMS) data with a focus on metabolomics or lipidomics applications. cosmiq is an R package that includes the following steps: combining spectra, detecting mz peaks on master spectrum, quantifying masses, retention times (RT) correction, computing the EIC matrix, detecting chromatographic peaks from EIC matrix and quantifying mz/RT features. The software can be integrated with the package xcms as an alternative preprocessing step.
