## Reference
Data File

SuperLab saves its data in a plain text file with fields separated by tabs. Here is a sample:
Lines 1 through 6 constitute a header. You can have more columns included in the data file than the sample above shows. To customize how the data file is saved, click on the Experiment menu and select Options.

- The Participant Response is the response provided by the participant, whereas the Correct Response column is what the correct response should be for that event.

- VERY IMPORTANT: the Reaction Time is measured from the onset of the last event that has reset the timer (see Event Editor's Input tab). This is different from how it was done in SuperLab 1.7x and 2. Please make sure to read the "Important" note in the Event Editor page.

- The Error Code is C for correct, E for error, SC for self-correct (participant provided the wrong response first than the correct one), or NR for no response. These codes can be customized in the Experiment Options dialog.

- A column will be added for each code that you have created.

- A column will be added for each trial variable, but this can be disabled in the Trial Variable Editor.
