Evaluating Chemical Terms functions can be done via the Chemical Terms Pipeline Pilot node. This type of node accepts a molecule as an input, and performs the specified calculation on it. The calculation is defined as a Chemical Terms function. The function can be specified in the Expression box of the Parameters section of the node.The result of the calculation is usually passed to an output node.

In the example below you can see the nodes of a simple workflow: the input node in this case is an SD Reader node; the calculation is performed by the Chemical Terms node; the output in this case case is directed into a HTML Table.
