To plan a CPS strategy, one typically sketches a "bracket" diagram detailing the synthetic route from starting segments to product protein (Figure ). The CPS bracket is a convenient shorthand and visualization tool, a blueprint referenced throughout a CPS project, and an unofficially required accompaniment to published syntheses. Despite their widespread use, there is no standard way to make these figures. Published syntheses vary both in visual style and in portrayed information, complicating the side-by-side comparison of different strategies. Drafting several possible brackets is extremely helpful for large proteins with multiple possible ligation sites, but this process is arduous (and prone to typos) in standard graphics software or by hand. As CPS increases in popularity, the field can greatly benefit from custom tools to plan and visualize syntheses.
