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?
