CONTEXT-DEPENDENT BASE CALLING - A simplified explanation of the abstract

This abstract first appeared for US patent application 18391487 titled 'CONTEXT-DEPENDENT BASE CALLING

The technology disclosed in this patent application is focused on context-dependent base calling, involving the use of k-mer-specific centroids to improve accuracy in sequencing.

  • Memory stores k-mer-specific centroids for k-mers.
  • Centroids are learned by training a base calling pipeline to represent base calls in k-mer-specific time series.
  • Predicted centroids are generated by transforming the time series and merging them on a sequencing cycle basis.
  • Training loss is determined by comparing predicted intensity values with known intensity values of base calls.
  • Updated centroids are stored and used at runtime to base call bases in a sequence based on k-mer context.

Potential Applications: - Improving accuracy in DNA sequencing. - Enhancing the efficiency of base calling processes in genomics research.

Original Abstract Submitted

The technology disclosed is directed to context-dependent base calling. The technology disclosed describes a system including memory storing k-mer-specific centroids for k-mers. The k-mer-specific centroids are learned by training a base calling pipeline to represent base calls of an already base called sequence in k-mer-specific time series, transform the k-mer-specific time series into predicted k-mer-specific centroids, merge the predicted k-mer-specific centroids on a sequencing cycle-by-sequencing cycle basis to generate predicted per-sequencing cycle intensity values, determine a training loss (e.g., a transformation loss) based on comparing the predicted per-sequencing cycle intensity values against known intensity values of the base calls, update the predicted k-mer-specific centroids based on the determined training loss, and store the updated centroids as the k-mer-specific centroids. The system also includes runtime logic that uses the k-mer-specific centroids to base call bases in a yet-to-be base called sequence in dependence upon k-mer context.
