3.3 Adding a Smiles Reader
The first node (or component) to add to the workflow is a SMILES reader.
1. In the Node Repository, open up the Schrödinger category by clicking on the triangle on
the left side.
2. Open up the Readers/Writers category.
3. Drag the Smiles Reader node into the workspace, and place it on the left.
The node has a title, an icon that represents the node, a set of “traffic lights” that indicates
the status of the node (status indicator), and a node number. The node description is displayed
in the Node Description tab. The icon has a triangle on the right side. This is a
point at which you can connect this node to another node, and represents the output of the
node (the triangle is like an arrowhead pointing out from the node). If you pause the
pointer over this triangle, it displays a brief description of the type of output, in a tooltip.
The node is also added to the Outline tab. As you add nodes, they are added to this tab,
which provides a view of the entire workflow.
