AnnotationSketch: a genome annotation drawing library.

SUMMARY: To analyse the vast amount of genome annotation data available today, a visual representation of genomic features in a given sequence range is required. We developed a C library which provides layout and drawing capabilities for annotation features. It supports several common input and output formats and can easily be integrated into custom C applications. To exemplify the use of AnnotationSketch in other languages, we provide bindings to the scripting languages Ruby, Python and Lua. AVAILABILITY: The software is available under an open-source license as part of GenomeTools (http://genometools.org/annotationsketch.html).
