FAQ: How can I add messages in Data Viewer
You can add messages in Data Viewer at any point by right clicking anywhere within the Trial View window and selecting the "Add Message" option.


This gives the option to add a new message in either trial relative time, Interest Period relative time, or EDF relative time. If the event time of the message is known, a message can easily be inserted as needed.

If you have a large number of messages to add, you can use Data Viewer's Message List feature to add multiple messages at once, on a participant-by-participant basis. Simply right click on the participant in the Inspector window and select Import Message List to select the formatted file containing the imported messages. See the Data Viewer manual (Help Menu -> Contents -> Working with Events, Samples, and Interest Areas -> Messages) to find information about how to format the import message list file.
