ETDQualitizer

This tool below allows you to calculate data quality for validations, collected with our PsychoPy procedure, locally in your browser (data is not uploaded to the cloud). Do as follows:

1. Select one or more files for which you want to calculate data quality (Once a selection is made, you can add files to/fully replace the current list of loaded files).
2. Enter the geometry of your setup.
3. Calculate the data quality measures by clicking the “Calculate” button.
4. Once calculated, a table with the results will appear on this page, and it can be downloaded by clicking “download results”.

A complete walkthrough including example data can be found here.
