 **Sam** had a scan performing language tasks, with alternating blocks of sense and nonsense sentences.The task timing has already been linked to the functional files (for more information on linking behavioral data and timing information, see [[paradigm files]]), so the next step is to open an activation map. This can be done straight from a command line, or by creating a task timing name (See [[Tasknames]]). For the purpose of this tutorial, you will create a task name which is a faster way to create the same activation again and again. **Sam** had a scan performing language tasks, with alternating blocks of sense and nonsense sentences.The task timing has already been linked to the functional files (for more information on linking behavioral data and timing information, see [[paradigm files]]), so the next step is to open an activation map.

The yellow refers to the first task and the green refers to the difference in activation from the first and the second task.  **5.11** Overlay the activation map on top of it.
