Hi Nicolas! How can we obtain the values of the threshold and the slope for HRD task? I can't find them in the HTML reports. Thanks for your help!

You can estimate threshold and slope in two ways:

Using the psi estimates that are updated online during the task. You can find these values in the EstimatedThreshold and EstimatedSlope columns from the result data frames.
You can re-estimate the values offline, you can check this example based on PyMC, see this example. We are using this approach most of the time as it allows to drop bad trials.

Also, this one details some basic analyses from the task data.
