checkCIF

checkCIF validates Crystallographic Information File (CIF) data to identify inconsistencies, errors, and unusual findings in crystal-structure determinations.

Key Features:

• Validation Reports: Generates automated validation reports from CIF files that identify errors and unusual findings in the structural data.
• ALERTS System: Produces ALERTS—concise messages that flag significant issues and provide explanatory text for each flagged item.
• FAIR compliance: Assesses CIF documentation to support FAIR principles (Findable, Accessible, Inter-operable, Reusable) for downstream analysis and independent interpretation.

Scientific Applications:

• Crystallographic data validation: Validates and flags issues in crystal-structure determinations reported in CIF format prior to dissemination or further analysis.
• Quality control for structural data: Supports detection of errors and unusual findings to improve the accuracy of deposited structural models.
• Support for reproducibility and peer review: Provides structured, actionable feedback to facilitate independent assessment and reproducibility of crystallographic results.

Methodology:

Analyzes deposited CIF files to generate validation reports that list ALERTS; implementations include IUCr checkCIF and PLATON/checkCIF, and ALERTS are produced as concise single-line messages with accompanying explanations.
