mineXpert

mineXpert provides visualization, integration, and analysis of mass spectrometry (MS) data to support proteomics, metabolomics, and structural biology research.

Key Features:

• Data Compatibility: Supports loading mass spectrometry data in (x,y) text format and mzML format.
• Visualization: Generates Total Ion Chromatogram (TIC) chromatograms and intensity=(mz, dt) colormaps, including support for ion mobility mass spectrometry representations.
• Data Integration and Isotopic Calculations: Provides multiple methods for integrating mass data and performs isotopic cluster calculations from chemical formulas through mass spectrum displays.
• Mass Peak Deconvolution: Performs deconvolution of mass peaks to facilitate inspection and quality assessment of spectra.
• Large Dataset Handling: Manages very large sparse datasets by slicing them into smaller chunks that replicate the original data without loss.
• Task Automation (JavaScript): Incorporates task automation capabilities within a JavaScript environment.

Scientific Applications:

• Bottom-up Proteomics: Supports MS1 spectral data inspection, quantitation measurements, and data mining for peptide-centric studies.
• Top-down Proteomics: Supports intact protein analysis including mass peak deconvolution and spectral interpretation.
• Structural Biology: Enables analysis and visualization of mass spectral data, including ion mobility-mass spectrometry, for structural studies.
• Metabolomics: Supports metabolite quantitation and mass spectral data mining from mzML and (x,y) datasets.

Methodology:

Processes mass spectrometry data in mzML or (x,y) text formats; performs TIC and intensity=(mz, dt) colormap visualization, isotopic cluster calculations from chemical formulas, mass peak deconvolution, slicing of very large sparse datasets into lossless chunks, and supports task automation in a JavaScript environment.
