GenomeTester4: a toolkit for performing basic set operations - union, intersection and complement on k-mer lists.


ABSTRACT: BACKGROUND:K-mer-based methods of genome analysis have attracted great interest because they do not require genome assembly and can be performed directly on sequencing reads. Many analysis tasks require one to compare k-mer lists from different sequences to find words that are either unique to a specific sequence or common to many sequences. However, no stand-alone k-mer analysis tool currently allows one to perform these algebraic set operations. FINDINGS:We have developed the GenomeTester4 toolkit, which contains a novel tool GListCompare for performing union, intersection and complement (difference) set operations on k-mer lists. We provide examples of how these general operations can be combined to solve a variety of biological analysis tasks. CONCLUSIONS:GenomeTester4 can be used to simplify k-mer list manipulation for many biological analysis tasks.
