Facilitating analysis and dissemination of proteomics data through metadata integration in MaxQuant

Area of Science:

• Proteomics
• Bioinformatics
• Data Science

Background:

• Metadata is crucial for proteomics data analysis and dissemination.
• Current metadata integration is time-consuming and lacks standardization.
• Inconsistent formats in public repositories impede data reuse and reproducibility.

Purpose of the Study:

• To present a user-friendly method for metadata integration in MaxQuant.
• To standardize metadata for proteomics datasets.
• To improve the reusability and reproducibility of public proteomics data.

Main Methods:

• Implemented metadata export in the SDRF (Sample and Data Relationship Format).
• Integrated SDRF file annotation into MaxQuant output tables.
• Developed a standardized approach for metadata creation and utilization.

Main Results:

• MaxQuant now provides user-friendly export of metadata as SDRF.
• Output tables are annotated with SDRF, enabling seamless downstream analysis.
• A simple and standardized method for metadata handling is established.

Conclusions:

• The implemented features facilitate easier data analysis.
• Standardized metadata significantly improves the reusability of proteomics datasets.
• Enhanced reproducibility of public proteomics data is achieved.
