Re: [HCP-Users] Quick questions
In the case of the 7T data, the 1/2/3/4 are just used to distinguish the different resting state runs, acquired in different scan sessions. The numbers are not intended to imply that each scan was acquired on a different day. We’d have to look, but I suspect that 1/2 were typically acquired on one day, and 3/4 on a different day.
