Hi AFNI experts,

I have a multiband resting state fMRI acquisition with the following details.

Scanner = Seimens MAGNETOM prisma
TR = 0.681 sec
Number of slices per volume = 54
Number of Volumes = 870
Slice Thickness = 2.5mm
Series = Ascending

I tried to preprocess this data with afni_proc.py by converting dicoms using dcm2nii command. I believe there is an error in the data conversion process because I see very strange connectivity results in the output of afni_proc.py.

Can you please guide me what is the exact procedure to create the AFNI compatible dataset from these DICOMS which is also taking care of the slice timing as it is a multiband acquisition.

Waiting for your reply.
Thank you.
