Building a Workflow

Example Workflow

To construct a workflow, drag nodes from the Workflow Node Library to the workflow canvas. Create links between nodes by clicking and dragging from one node’s outgoing connector to another node’s incoming connector.

It is also possible to create a new workflow from all or portions of an existing workflow. In an existing workflow, you can click the Save Workflow As button on the Toolbar and enter in the new workflow name when prompted. Alternately, you can copy one or more nodes from a workflow by clicking the Copy button (or [CTRL]+C) on the Toolbar, opening a different workflow from Atrium, then clicking the Paste button (or [CTRL]+V) on the Toolbar. The pasted nodes are pre-selected, so you can immediately drag them all to a new location on the canvas.

Note

All workflows must begin with one or more Read File nodes.

Example of Creating a Workflow

Suppose you wanted to examine the relationships between attributes for a given dataset. The workflow could be comprised of the following three nodes: a Read File node to read in the data, a Univariate node to create frequency distributions, graphs, as well as summary statistics, and a Bivariate node to create a two-way frequency table, a means table, and a correlation matrix.

Drag and drop a Read File node onto the canvas. Complete the proper configuration.

Drag and drop a Univariate node and then configure it after creating a link to the Read File node.

../_images/bivariateNode.png ../_images/buildingAWorkflow_bivariate.png

Drag and drop a Bivariate node and then configure it after creating a link to the Read File node.

When you are finished configuring each of the nodes and all links are created, your workflow is ready to run.
