SearchGUI

SearchGUI facilitates peptide and protein identification from mass spectrometry-based proteomics data by configuring and executing OMSSA and X!Tandem searches against protein databases.

Key Features:

• Simultaneous Engine Execution: Executes OMSSA and X!Tandem searches concurrently to enable combined analysis across engines.
• Search Parameter Configuration: Allows specification of search parameters tailored to experimental needs for peptide/protein identification.
• Execution Against Protein Databases: Runs mass spectrometry data searches directly against user-provided protein databases using OMSSA and X!Tandem.
• Result Compilation: Compiles and consolidates search results from multiple engines for downstream analysis.
• Large-Scale Data Handling: Supports analysis of complex and large-scale mass spectrometry datasets.

Scientific Applications:

• Protein Characterization: Identification of peptides and proteins from MS/MS spectra for protein-level annotation and characterization.
• Post-Translational Modification Analysis: Detection and interpretation of post-translational modifications via configured search parameters.
• Biomarker Discovery: Generation of protein identification results suitable for candidate biomarker selection in proteomic studies.
• Large-Scale Proteomics Studies: Application to high-throughput proteomic datasets to support large-scale protein identification efforts.

Methodology:

Configure search parameters, execute mass spectrometry data searches against protein databases using OMSSA and X!Tandem, and compile the resulting identifications.
