Galaxy workflow editor. Galaxy's workflow editor provides a graphical user interface for creating and modifying workflows. The editor has four areas: navigation bar, tool bar (left column), editor panel (middle column), and details panel. A user adds tools from the tool panel to the editor panel and configures each step in the workflow using the details panel. The details panel also enables a user to add tags to a workflow and annotate a workflow and workflow steps. Workflows are run in Galaxy's analysis workspace; like all tools executed in Galaxy, Galaxy automatically generates history items and provenance information for each tool executed via a workflow.
