GeneValidator

GeneValidator evaluates gene predictions in newly sequenced genomes by performing comparative analyses against reference protein databases (e.g., SwissProt) to detect discrepancies and likely errors that could affect downstream analyses.

Key Features:

• Automated identification of problematic predictions: Performs multiple comparative analyses of predicted genes against public sequence databases such as SwissProt to flag inconsistent or suspicious gene models.
• Comprehensive reporting: Produces per-gene reports that include quantitative statistics and visual graphs summarizing discrepancies and metrics relevant to prediction quality.

Scientific Applications:

• Improving gene annotation accuracy: Detects likely errors in gene models to increase the reliability of genome annotations in newly sequenced organisms.
• Prioritizing manual curation: Ranks or highlights problematic predictions to focus biocurator efforts on the most questionable gene models.
• Supporting downstream analyses: Identifies prediction inconsistencies that could bias functional, comparative, or evolutionary studies.

Methodology:

Performs comparative genomics analyses by comparing predicted genes to established sequences in public databases (e.g., SwissProt), identifies discrepancies and potential errors, and computes statistics and visualizations for each gene.
