Abstract

fetched live from OpenAlex

Understanding the function of a locus is an issue in molecular biology. Although numerous molecular data have been generated in the last decades, it remains difficult to grasp how these data are related at a locus. In this study, we describe an analytical workflow that can solve this problem using the knowledge available at the single-nucleotide polymorphism (SNP) level. The underlying algorithm uses SNPs as connectors to link biological entities and identify correlations between them through a joint bioinformatics/statistics approach. We demonstrate its application in finding the mechanism whereby a mutation causes a phenotype and in revealing the path whereby a gene is regulated and impacts a phenotype. We translate our workflow into publicly available shell scripts. Our approach provides a basic framework to solve the information overload problem in biology surrounding the annotation of a locus and is a step toward repurposing GWAS data for new applications.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
