How much data, in what structure, and which file format?
You can find different download options for your experiment. Which download you should choose depends on three things:
Which data do you need? All participants for your experiment? Only the results for one task? One participant? To find the file containing only the data you need, simply go to the respective page in your experiment, and look for the downloads icon (). For example, to get the data for the first participant to complete a task, first find the task in your list of tasks, and open its configuration page. Then go to the participants page for that task, and navigate to the participant you're interested in.
How should the data be structured?
- In the versatile tree structure, all variables and metadata data can be accessed.
- The simple table structure organizes the values in rows and columns.
- The uniform annotations structure describes an annotation for each stimulus, or set of two or three stimuli.
- The matrix structure contains one-, two- or three- dimensional arrays.
- The events structure contains a list of all events that happened during the task.
- The metadata structure describes participants and recruitment information.
In what filetype should the data be stored? This depends on which application or programming language you will use to open the file.
- To view the data in a spreadsheet such as Microsoft Excel or Google Sheets, select csv (comma separated values).
- The .mat format stores data for for Matlab.
- Events can be downloaded in the log format which is a simple tab-delimited text file.
