Hi PT,
Thank you so much for your reply. Yes,the FMRIprep command above should be outputting the EPIs in alignment with the subject anatomical , basically in a "native" subject space).
And the A and B outputs are:
A:
N-1 header file 'sub-1_task-checker_acq-TR156_space-T1w_desc-brain_mask.nii.gz', num_fields = 2
name offset nvals values
------------------- ------ ----- ------
qform_code 252 1 2
sform_code 254 1 2
B:
N-1 header file 'sub-1_desc-preproc_T1w.nii.gz', num_fields = 2
name offset nvals values
------------------- ------ ----- ------
qform_code 252 1 1
sform_code 254 1 1
Many thanks for your help!
