course 4.0.2.1

A lightning presentation on CPAN modules that help you handle spans and sets. This is of interest to those of you who work with objects with spatial coordinates (clones, contigs, alignments, etc) or objects identified by an index set (array probes, ordered features, etc). Focus will be on demonstrating how to use the Set::IntSpan module to calculate coverage and coverage gaps and to find runs in probe sets. Other CPAN modules that implement sets and multisets will be mentioned.

4.0.2.1 Spans and Sets

tools

Set::IntSpan Implements sets of integers, optimized for sets with long runs of consecutive elements.

Set::IntRange Also implements sets of integers, but on a fixed interval. Implements overloaded operators.

Set::Window Implements an set of consecutive integers. This module is ideal when working with algorithms that employ sliding windows. Set::Window has functions to move and shrink the window.

Set::Window Implements multisets (sets in which objects may appear more than once).

CPAN Set:: Namespace Many modules implement sets. Explore CPAN to find your favourite.
