GenoPipe: identifying the genotype of origin within (epi)genomic datasets

Area of Science:

• Genomics
• Bioinformatics
• Experimental validation

Background:

• Genomic data generation has increased exponentially, leading to a rise in experimental errors.
• Technical mistakes in genomics assays (e.g., contamination, mislabeling) are difficult to detect post-experiment.
• Experimental confidence is crucial for scientific discovery.

Approach:

• Developed the Genotype Validation Pipeline (GenoPipe), a suite of heuristic tools.
• GenoPipe operates on raw and aligned sequencing data.
• Characterizes the underlying genome of the source material using inherent DNA markers.

Key Points:

• Identifies unique genomic markers such as insertions, deletions, and single nucleotide polymorphisms (SNPs).
• Validates experimental annotations by comparing sequenced data to known genomic markers.
• Recues erroneously annotated experiments by forensic ascertainment of DNA markers.

Conclusions:

• GenoPipe provides a robust method for validating and correcting genomic experimental data.
• Enhances confidence in experimental results by identifying and rectifying errors.
• Ensures the integrity and reliability of genomic datasets for future research.
