question about use_spontaneous and control video

[NxNiki]

I am trying to add clusterless data during sleep as the inference (test) data set. A few questions about the related code:

With regard to use_spontaneous:

brain_decoding/src/brain_decoding/dataloader/movie.py

Lines 70 to 72 in bfba0bf

	if self.use_spontaneous:
	categories.append("Control1")
	categories.append("Control2")

Does this enable the use of control videos? What are the control videos (do they have the 8 concepts as in the 24)?
