 To record data:\\
-  * select Physio ->
+  * select Physio -> Record physiological signals
+  * wait until the Tech has prepped the scanner
+  * press 'w' at the prompt, to wait for the scanner
+  * switch to your other program's window and start your task and the scanner as normal
+  * when the task is done, go back to CIGAL's window and enter
+    * <Control>E -- this will cause CIGAL to end its recording
+  * in the data saving window, enter the scanner's __Exam number__ and the scanner's __series number__ for the scan you just finished (ask the Tech if you are not sure). You can ignore all the other fields in the save data window.
+CIGAL will put all the data it records in one session in a folder named with the __Exam number__ you entered in the  saving data dialog. You will see separate text files for each channel of recorded data for each scan series. Each text file has 2 columns of numbers: time (in secs) and the analog signal value. Time=0 is the time that the first MR image was acquired (make sure your __disdaq__ and __TR__ settings in CIGAL match your scan protocol settings (see those parameters in menu: Settings -> Scan settings).
+The other important output file is a "pdigm" file for each scan series recorded. The "pdigm" data file contains a copy of all your CIGAL settings, and all of the data recorded during each run. For a graphical view of your physio data you can display the data contents of a "pdigm" file using:\\
+  * Physio -> Show behavior -> Saved pdigm file
