Using DataMatrix with Tobii_Pro eyetracker?

Many thanks to @sebastiaan for contributing another excellent tool!

My question: Has anyone used Data Matrix for processing/analyzing data from a Tobii eyetracker?

In order to be able to compare the Tobii vs. Eyelink output files, I tried to read the Eyelink edf files of the semantic_pupil experiment https://github.com/smathot/semantic_pupil/tree/master/analysis, with no luck. I cannot convert the .edf files to .asc. Could someone, perhaps, upload one as .asc (or other readable format)?

I am also attaching two screenshots of a Tobii X3-120 output .tsv file.

Note that missing (-1) values in pupil size are due to Tobii X3-120 reporting pupil size only in bright pupil mode which is used only every third sample. Thus although this model records eye gaze at 120Hz, it records pupil size at only 40Hz -as this is only a pilot study, I guess this is not too important.



Any advice would be more than welcome!

Best,

Alexandra

  • Hi Alexandra,

    Here's a link to one of the datafiles from the semantic-pupil experiment, converted to .asc. This is done with a utility called edf2asc, which you can download for free from the SR Research forum. (But this does require you to register on their forum.)

    It should be straightforward to build an adapter for the EyeLinkParser such that it can read the .tsv files above. (Similar to how this is done for the EyeTribeParser.) Could you upload one complete datafile so that I can see what it looks like exactly?

    Cheers!

  • Hi Sebastiaan,

    Thank you very much for your imediate reply and the asc output file!

    I will have study it, as well as the EyeTribeParser...

    Here you can find a Tobii_Pro output file https://www.dropbox.com/s/760i00vmabelsao/subject-101-3_TOBII_output.tsv?dl=0 (it wouldn't let me upload it here).

    Thanks again for everything.

    Best wishes,

    Alexandra

  • Hello Sebastiaan,

    Thanks for the useful and open-source toolbox.

    I'm also using data from Tobii, however I have the data en txt format.

    Since the name of the variables are different, my question is how can I rename the variables in order to match with my variables names?

    For example, the first error I get: No column named "set_size"

    I imagine that set_size refers to the pipul width of every trial?

    Then I guess I need to rename the variable set_size for PupilWidth as in my file

    Thank so much in advance!

    Hi Melanni,

    It's not clear to me what you're doing exactly. It sounds like you're using some script to parse some data files and that something goes wrong. But you'll have to be a lot more specific for us to be able to help you! What are you doing exactly?

    Cheers!

  • Hi Sebastiaan,

    Thanks for your response, I'm sorry if I was not clear.

    I have eye-tracker data from Tobii Pro Glasses (I attached the file of one subject).

    I just want to preprocesses the pupil-size signal (column PupilWidth) by getting rid of the blinks, smooth the signal, and all the necessary steps for later on use this signal as a regressor for fmri data.

    As I understood this is a toolbox able to perform such analysis with my data..?

    Cheers!

  • Hi Melanni,

    The EyeLinkParser parser a variety of formats, but not this one. So no, you cannot really use it, not without extensive modifications to the code. You could load the data into a DataMatrix object and then use series.blinkreconstruct() and other functions to process the data, and then save it again.

    However, this will require some knowledge of numerical computing with Python, and the nature of your questions suggests to me that you don't have this at the moment. Is there someone in your lab who can help you with this?

    Cheers!
