Extract Features Function

The Extract Features function, located in the Functions section of the Toolkit panel, adds a new feature extraction function to an existing script. See its sister template topic, Extract Features as Sequences, for detailed information and use cases.

Unlike its sister template, which prompts you to add a file, the Extract Features function allows you to specify a sequence source using one of four buttons: File, Sequence Text, Variable and Function. See Write to Results File for more information on using these buttons.
