I am working with the Neuropixel data, and the “Functional Connectivity” experiment paradigm. In that, there is a block of 10 minutes, where the “natural_movie_shuffled” is presented. I was curious about
- how the shuffled frames were obtained, and if the same shuffled frames were presented in all experiments, or different shuffles were obtained on each day?
- Since there were 20 repeats, were all these 20 repeats the same “movie” or was each presentation different?
In trying to access the .nwb file (for example session -778240327), I see the “frame” entry inside “/intervals/natural_movie_one_shuffled_presentations” to simply increase from 0 to 900, which I assume is just the frame number for the presentation, and does not reflect frameIDs with respect to the original video. I want to access the information of what visual cue/frame was present at each time point.
I tried the idea from this link , but it did not work since, I assume that was for the calcium imaging experiments, where the shuffled movies were not presented.
Thanks in anticipation,
