LC-MS/MS Peptide and Protein Identification Data for Rotavirus DS-1 VP7

A collection of raw LC-MS/MS data for the rotavirus DS-1 VP7 protein, with peptide-spectrum matches identified against the NCBI human protein database. The data is organized into three tables: Spectra, Proteins, and Summary, detailing individual peptides, identified proteins, and search parameters. The dataset is provided as a 384.3 KB XLSX file.

Use Cases

• Compare observed and theoretical precursor masses in the Spectra table to validate peptide identification algorithms.
• Analyze sequence coverage and total spectral counts in the Proteins table to assess protein abundance and identification confidence.
• Correlate modifications listed in the Spectra table with cumulative log-probabilities in the Proteins table to study post-translational modifications.
• Use the Summary table's search parameters to replicate or benchmark mass spectrometry data processing workflows.

Strengths

• Data is structured into three distinct analytical tables (Spectra, Proteins, Summary) for organized exploration.
• The dataset is shared under a permissive CC BY 4.0 license, enabling reuse and redistribution.
• Includes specific protein targets relevant to rotavirus research, such as DS-1 VP7 and Signal Peptidase Complex components.

Limitations

• The dataset is small in scale at 384.3 KB, indicating limited sample depth or scope.
• The exact row counts and column definitions for the three tables are not provided, complicating initial assessment of data volume and structure.
• The data appears to be from a single, specific experimental analysis, limiting generalizability.
