Projects are the unit of organization within Transcriptic. A project might correspond to a whole paper, a particular trial, or an isolated set of experiments for a particular hypothesis — it's up to you to decide how to split up your experiments into projects.
An organization can have many different projects and one project can have many data-producing, as well as non-data-producing, runs. Within a project you can see runs that are scheduled to be executed, ones that have already been completed, and ones that have been cancelled. Clicking the "Launch a Run" button from within a project creates a new run in that project.
