I went through the tutorial ecephys_quickstart.ipynb
, and found that the indices for natural scenes in the downloaded data ( scene_presentations["frame"]
in the notebook) range from -1 to 117, but I think the indices should actually range from 0 to 117, since there are only 118 natural scenes and the argument for cache.get_natural_scene_template
ranges from 0 to 117. (All ranges above are inclusive.) What does -1 mean?
