Eyetracker-Scripts-HowTo.md

 The blocks software includes some scripts that process gaze sequences exported from TOBII. Their main purpose is to align TOBII gaze sequences with the videos collected from our top-down camera setup, allowing us to examine gaze behavior during each of the actions in the video instead of overall behavior during the entire video.
 
 **EXAMPLES**
+In `egs/prepare_eyetracker_data`, the pipeline we use to pre-process the TOBII gaze samples and turn them into more interpretable measurements is automated from beginning to end.
 * How to run everything at once:
     ```console
     user@host:~/repo/blocks/egs/prepare_eyetracker_data$ ./run.sh    
     ```
 * How to pre-process a TOBII export file and move it to the remote server:
     ```console
-    user@host:~/repo/blocks/egs/prepare_eyetracker_data$ ./run.sh --start_at=1 --end_after=4 
+    user@host:~/repo/blocks/egs/prepare_eyetracker_data$ ./run.sh --start_at=1 --stop_after=4 
     ```
 * How to post-process eyetracker data to get gaze statistics:
     ```console
-    user@host:~/repo/blocks/egs/prepare_eyetracker_data$ ./run.sh --start_at=5 --end_after=6
+    user@host:~/repo/blocks/egs/prepare_eyetracker_data$ ./run.sh --start_at=5 --stop_after=6
     ```
