Combine GASF and GADF into a two-channel array

Creates a two-dimensional array containing both the Gramian Angular Summation Field (GASF) and the Gramian Angular Difference Field (GADF) produced from a single ONT tail chunk. Using both representations increases the sensitivity of the CNN classification by overcoming the limitations of each method individually.

Usage

combine_gafs(tail_chunk)

Arguments

tail_chunk

Numeric vector. A 100-element signal chunk representing a fragment of the poly(A) tail.

Value

An array of dimensions (100, 100, 2) where the first channel contains the GASF and the second channel contains the GADF, both produced by create_gaf.

create_gaf for individual GAF computation, create_gaf_list for batch processing, predict_gaf_classes for downstream CNN classification

Examples

if (FALSE) { # \dontrun{

ninetails::combine_gafs(tail_chunk = tail_chunk)

} # }
