Tandem2XML

Tandem2XML converts Tandem XML output into pepXML to enable interoperability of mass spectrometry (MS) proteomics data across pepXML-based analysis tools for protein identification, quantitation, and post-translational modification (PTM) analysis.

Key Features:

• Format Conversion: Converts Tandem XML output into the pepXML format to allow downstream processing by pepXML-compatible tools.
• Integration with Trans-Proteomics Pipeline (TPP): Operates within the TPP ecosystem to integrate Tandem-to-pepXML conversion into standardized proteomics workflows.
• Standardized Data Formats: Uses open formats (Tandem XML and pepXML) to promote interoperability across operating systems and instrument vendors.

Scientific Applications:

• Protein Analysis: Facilitates protein identification, quantitation, and detection of post-translational modifications by converting search results into pepXML for downstream interpretation.
• Large-scale Reproducible Proteomics: Supports reproducible and scalable MS proteomics analyses by enabling integration of Tandem search outputs into TPP-based pipelines across desktop and cloud environments.

Methodology:

Tandem2XML performs programmatic conversion of Tandem XML to pepXML as part of the Trans-Proteomics Pipeline (TPP), within an open-source framework that emphasizes standardized data formats and benefits from TPP visualization features.
