COMSPARI

COMSPARI facilitates comparison of mass spectral and chromatographic datasets to detect subtle compositional differences in metabolomics and proteomics data.

Key Features:

• Data Compatibility: Supports netCDF and ASCII file formats for input data.
• Visualization of Mass Spectral Datasets: Visualizes mass spectra and chromatograms from matched samples to reveal small differences.
• Enhanced Detection Capabilities: Identifies significant peaks and subtle compositional differences more efficiently than manual visual inspection.
• Spectral Retention Information Comparison: Compares spectral retention information to aid detection of differences between related samples.

Scientific Applications:

• Metabolomics Studies: Compares extracts from wild-type and genetically modified strains of Saccharomyces cerevisiae to identify distinct mass spectral features.
• Peptide Digest Analysis: Compares LC/MS data from peptide digests performed with identical substrates but different enzymes to detect compositional differences.

Methodology:

Processes netCDF and ASCII input, visualizes mass spectra and chromatograms, and detects significant peaks and compositional differences between matched samples.
