All MRI data at time 1 were collected with a 3T Siemens scanner. At time 2, data from 21 participants were collected using the same Siemens scanner, and data from 98 participants were collected using a 3T General Electric (GE) scanner. For the Siemens scanner, the following parameters were used: T1-weighted (TR=2,530 ms, TE=2.8 ms, flip angle=10 degrees, voxel size=1.0×1.0×1.0 mm, frames=256, FOV=256×256), resting-state (TR=2,000 ms, TE=30 ms, flip angle=77 degrees, voxel size=3.4×3.4×3.5 mm, frames=180, FOV=384×384, scan duration=360 s). For the GE scanner, the following parameters were used: T1-weighted (TR=8.46 ms, TE=3.248 ms, flip angle=12 degrees, voxel size=1.0×1.0×1.0 mm, frames=252, FOV=256×256), resting-state (TR=2,000 ms, TE=30 ms, flip angle=77 degrees, voxel size=3.4×3.4×3.5 mm, frames=5580, FOV= 64×64, scan duration=360 s). The resting-state scan was acquired after a localizer scan to avoid carryover effects. During the resting-state scan, participants were asked to keep their eyes open, relax and not to think of anything in particular.
