Dear AFNI experts,
I have two datasets with a different acquisition slice order (tpattern). I would like to make sure that the slice timing correction with 3dTshift is well done.
1. First dataset.
TR=2 seconds
number of slices=35
slice order= Interleaved (1,3,5,7...35; 2,4,6,8...34).
Command used:
3dTshift -tpattern Alt+z -Fourier -prefix s_001_stc.nii s_001.nii
2. Second dataset.
TR=2 seconds
number of slices=37
slice order= Interleaved with jumps of 5 slices (1, 7, 13, 19, 25, 31, 37; 2, 8, 14, 20, 26, 32; 3, 9, 15, 21, 27, 33; 4, 10, 16, 22, 28, 34; 5, 11, 17, 23, 29, 35; 6, 12, 18, 24, 30, 36).
Command used:
3dTshift -tpattern Alt+z -Fourier -prefix s_001_stc.nii s_001.nii
I am using the exact same tpattern for both datasets. Is this correct considering that the second dataset has more interleaved "jumps"?
Is there a way to do a sanity check to know if the correction is well done?
Note: The to3d program considered both datasets as Alt+z.
Thanks in advance.
Kind regards,
Karel
