#align

Synopsis

align provides functions to align two list of elements using the Needleman-Wunsch algorithm.

Functons

proba

align:proba(gap, match, a, b)

Evaluates a and b as lists of elements and aligns them using the Needleman-Wunsch algorithm, then returns the optimal alignment probability.

gap is evaluated as a number and specifies the gap penalty.

match is evaluated as a number for each pair of elements. The context element is an item form a and the item from b can be retrieved with the function other.

score

align:score(gap, match, a, b)

This function aligns two lists. The difference from align:proba is that this function returns the alignment score.
