lcmsWorld

lcmsWorld visualizes liquid chromatography–mass spectrometry (LC-MS) data in three dimensions to represent retention time alongside mass/charge ratio and detected ion counts for proteomics and metabolomics analysis.

Key Features:

• Three-Dimensional Visualization: Represents retention time as a third dimension together with mass/charge ratio and detected ion counts to visualize chromatography-MS datasets.
• Utilization of Graphics Hardware: Harnesses graphics hardware for rapid, smooth rendering of large-scale LC-MS datasets.
• Preprocessing and Multi-Level Detail Access: Performs preprocessing to optimize data handling and provides access to dataset regions at multiple levels of detail.
• Dynamic Data Navigation: Implements automatic data loading and level-of-detail selection to manage which portions of the dataset are displayed during exploration.
• Quality Control and Verification: Enables manual graphical examination of raw data to assist quality-control checks and verification of computational analysis results.

Scientific Applications:

• Proteomics: Provides 3D visualization of LC-MS datasets to reveal patterns and anomalies in proteomics experiments.
• Metabolomics: Provides 3D visualization of LC-MS datasets to reveal patterns and anomalies in metabolomics experiments.

Methodology:

Preprocesses LC-MS data for multi-level detail access and uses graphics hardware for real-time 3D rendering with automatic data loading and level-of-detail management.
