I am sorry that in the following parameters, I made a type error. The thickness/gap should be 3.5/0.7 mm. If you have used 3.5/0.6, it OK.
Please note that an FOV of 200*200 is sometimes small.

The following parameters are what we are using on a SIEMENS 3T trio scanner. 33 axial slices, thickness/gap = 3.5/0.6 mm, in-plane resolution = 64 × 64, TR = 2000 ms, TE = 30 ms, flip angle = 90, FOV = 200 × 200 mm, volumes = 240 (480 s). I strongly recommend that the RS-fMRI session is placed before the task sessions.
