2) In the Save As dialog box, browse to the directory in which you want to save the document.

3) In the File name text box, type in the name for the document.

4) Click Save.

Tip: The viewing session can also be saved by clicking the Save Viewing Session As tool on the standard toolbar.

3.5 Importing an EyeLink Data File

EyeLink EDF files can be imported into an already opened Viewing session or, if no

Viewing session is open, a new one will be created for you when the data files are imported.

To import an .EDF file,

1) From the menus, choose:

File

→ Import Data → EyeLink File(s)

2) In the Load dialog box, browse to the location of the EDF file that you want to import and select it.

3) Click Load.

Tip: EyeLink data can also be imported by clicking the Import EyeLink Data File button on the standard toolbar, or press Ctrl+I.

Note: The time it takes to load the data files will depend on their size and heavily on whether or not you are loading samples from the data file. A 60 minute, binocular, 500Hz recording will take 3 – 4 minutes to initially parse the data file if loading all events and samples. Once you have saved the viewing session, reloading the session takes a fraction of the time because the data is in a format optimized for the Data Viewer.
