[th-2 Dataset 3] Size of the platform and cue locations

Thanks a lot for sharing this great dataset!

We are doing analyses and modelling of th-2-Dataset_3 and are interested in the size of the platform and the exact cue locations.

1.) What are the dimensions of the circular platform in the cue rotation task? The paper states a diameter of 30cm, while dataset_metadata.xlsx claims 35cm.

2.) Could you please let us know if the starting location of the LED cue was randomized. I.e., which LED panels (up, down, left, right panel in camera coordinates) were active during the different epochs for each session of the cue rotation task? 

Currently, we know if there was a CW or CCW rotation. From our analysis, we assume that the cue rotation likely always starts on the upper (north) panel, but this is based on some assumptions.

Alternatively, if this info is not available, we could also have a look at the videos ourselves.

3. It would be great, if you could provide one example video (the entire video dataset is probably too large), so we can get a better intuition of the data. For instance, we were wondering, if there are shadows or glows from the active LED, that could affect our intended model. 

Thank you!
