Abstract
SUMMARY: GFA has emerged as a standard format for the exchange of genome assemblies and sequence graphs. To encourage further adoption in high-performance software we have developed an open-source C++ library for GFA and a set of utilities for summarizing and manipulating the format. AVAILABILITY: The gfakluge source code is freely available under the MIT license at https://github.com/edawson/gfakluge. It has been tested on both Mac OS X and Linux.
