‍Where Is My Data?

‍SuperLab 7 automatically saves all collected data in a folder that has the same name as your experiment followed by “data”. For example, if your experiment is named “Stroop.sl7”, then all data is saved in folder “Stroop data”.

‍Important: If you move the experiment file, always move the data folder with it. If you do not, SuperLab 7 will not be able to display the data and will create a new folder if you run the experiment again.

‍If you run an experiment in pilot mode, the data is saved into a folder named “Pilot” inside the data folder.

‍Inside The Folder

‍Within this data folder, SuperLab creates “session folders”. A session folder is added every time you run an experiment and contains one or more of the following items:

• The behavioral data file (reaction time, responses, etc.)
• Vocal responses (if using microphone)
• Screen recordings (if using the X7 edition of SuperLab)

‍The Behavioral Data File Format

‍SuperLab saves the behavioral data in a plain text file with fields separated by tabs. This makes it easy to import into a spreadsheet or to write custom software to parse it. The file format produced consists of:

‍▪ A file header.

‍▪ A data header that describes the columns of data of data that follow.

‍▪ The actual data.

‍The file header and data header are always separated by a blank line.

‍File Header Details

‍A line in the file header always starts with a period (dot) followed by a keyword. Here is description of all keywords:

‍▪ Experiment Name, followed by one field; this is the experiment’s file name.

‍▪ Participant Name, as entered when you run the experiment, or “n/a” if no name is entered.

‍▪ Session ID, as entered when you run the experiment, or “n/a” if none is entered.

‍▪ Date, followed by two fields to indicate the date and time.

‍▪ Resolution, followed by two fields to indicate the width (X) and height (Y) in pixels of the display.

‍▪ OS, followed by two fields that indicate the operating system and the processor (CPU).

‍The following keywords apply only to SuperLab X7 when using a Tobii eye tracker:

‍▪ Tobii Calibration Validation Accuracy (L/R)

‍▪ Tobii Calibration Validation Precision (L/R)

‍▪ Tobii Calibration Validation Precision (RMS L/R)

‍Please see the Tobii documentation for information on interpreting these numbers.

‍Rows & Columns

‍SuperLab adds one row of data for each participant response or expected response.

‍In addition to the standard data (Block Name, Reaction Time, etc.), a data file will contain the following additional  columns:

• One column is added for each tag set that you create; the column will show which tag you have applied to a trial.
• Two columns are added for each stimulus list that you create. The first one will show the list item that was used on that particular slide, the other will show the tags that you applied to that list item, if any.
• One column is added for each trial variable that you create.

‍A Tip for Parsing The Data File

‍Cedrus expects that more keywords will be added to the file header in future versions of SuperLab. If you are writing software to parse the data file, we suggest that your code not look for a fixed list of keywords. Instead:

‍▪ Look for a period at the beginning of each line.

‍▪ Get the keyword that follows the period. If your code does not recognize or care for the keyword, then simply ignore the rest of the line.

‍▪ If the next line does not start with a period, then you have finished parsing the file header.

‍This approach will make your code more future-proof regardless of how many new keywords get added to the file header.
