Gradual rotations issues #69

Closed thartbm closed 5 years ago

thartbm commented 6 years ago

Gradual rotations are increased trial-by-trial in the actual experiment, BUT:

  1. The rotation for the trial is not recorded: the maximum rotation is recorded. We want the actual rotation on that trial.

  2. The cursor keeps rotating more and more. We have a paradigm with 100 trials for a gradual rotation to 30 degrees, but at trial 70 we get about 70 degrees rotation. It should stop increasing at the maximum rotation.

So for each trial:

if rotation >= 0:
    sign = 1
else:
    sign = -1

trial_rotation = sign * max(abs(task_rotation), trial_number)

And record that trial rotation in the data.

Gradual rotations were rounded to whole numbers because initial and final rotations were integers causing Python to generate some pretty weird gradual rotations.

Fixed by converting to floats.
