This script extends blink, fixation and gaze data by adding an additional column "world_frame_index" to every CSV file. This column indicates the closest available world video frame for each data sample.
To install the dependencies, run the following
pip install numpy pandas
Before executing the file, customize the file paths in the beginning of the file. If you do not want one of the files to be edited, e.g. the fixations file, then set the according path to "None", i.e. fixations_path = None
