 Blastering image generator, BRIG, is a cross-platform application that allows users to quickly and easily generate comparative genomic images from a variety of prokaryotic genomes. It is designed to work with both finished and unfinished genomes, allowing researchers to compare up to 200 genomes simultaneously. Additionally, BRIG can display draft genome assembly information such as read coverage, assembly breakpoints and collapsed repeats. This makes it ideal for visualizing complex genomic data sets.
