-and performing actions on headers (for replacement), are controlled by a text file called 
-a deid recipe. If you want a reminder about how to write this text file,

-we will walk through basic actions that might say something like:
-
- > Replace Field A with the output of a function called generate_uid
-
-Specifically, we can define a set of REPLACE and ADD actions:
-
-```
-FORMAT dicom
-
-%header
-
-REPLACE StudyInstanceUID func:generate_uid
-REPLACE SeriesInstanceUID func:generate_uid
-ADD FrameOfReferenceUID func:generate_uid
-```

 Here is a quick example to show using deid to update a frame of reference UID,
 and instance UIDs across a set of datasets. We aren't doing any filtering, we are just going to
 change field with a value derived from a function. This example
