If anyone is working on CamCan data, I wonder what type of preprocessing you are using to clean the data, given that the data is already clean but still looks very noisy from t =22 to the end!
I have not used the data myself. However, you should be sure to read this: https://www.sciencedirect.com/science/article/pii/S1053811915008150 and use the MaxFiltered data. In addition, you may way to do some cleaning (eye blinks, heartbeats, etc.) if you are not using the pre-processed data.
