MALDI-TOF Spectra for Converter Validation from Argentine Clinical Labs

311 MALDI-TOF mass spectra peak lists from clinical microbiology routines in Buenos Aires, Argentina, used to validate a file converter for the CDC's Microbenet tool. The data includes 56 spectra from a national reference laboratory and 255 from a pediatric hospital, plus 16 isolates from rare species. Author Pablo Martin Cassanelli published the dataset on figshare in April 2026.

Use Cases

• Validate file format converters for mass spectrometry data based on the described peak lists in xls, mzXML, and mzml formats.
• Benchmark microbial identification tools using spectra from rare species isolates mentioned in the description.
• Assess data interoperability for web-based clinical tools based on the reference to CDC's Microbenet compatibility.

Strengths

• Includes 311 distinct MALDI-TOF spectra from real clinical workflows.
• Covers data from two distinct Argentine healthcare institutions, providing a multi-source perspective.
• Contains 16 isolates from rare species previously unidentifiable by standard databases.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale ML tasks.
• Data may reflect geographic and temporal bias inherent to the two specific Buenos Aires hospitals.
