Mosaic's ordering system allows users to set up orders, specifying the samples they want and the format they want them in. Mosaic determines the operations required and turns this into a workflow, which is automatically passed to the workflow manager. Orders are validated for a wide variety of potential problems (for example insufficient compound exists, labware would overflow, compound transfers below minimum accurate pipetting volume for a machine), allowing correction or alternative planning before the processing begins. Users can track the progress of their orders, and view feedback on any items that could not be fulfilled. Mosaic can be closely integrated with structure databases and results analysis systems to provide seamless workflow management. For example follow-up orders can be created automatically by the analysis system based on the experimental results. The ordering system can be deployed to users remote from the dispensary, globally if desired. Web-browser based user interfaces make deployment easy. Customisable wizards enable frequent inventory management operations to be setup once and executed with just a few mouse clicks. For example a supervisor can search for plates that need to be replenished based on criteria such as age, number of wells containing less than a threshold volume or the number of freeze-thaw cycles the plate has experienced.
