Rick,
One additional thing that I did not mention in my original posts is that this data was also taken on a 32-channel coil vs. other studies were done with a 12-channel coil. I do not think that this matters - but I thought I should give you as much info as possible.
Here is the information from 3dinfo:
1. 3dinfo hf01_mprage_ss+orig.| grep -e extent -e orient
++ 3dinfo: AFNI version=AFNI_2011_12_21_1014 (Nov 19 2014) [64-bit]
third (z) = Inferior-to-Superior [-orient LPI]
R-to-L extent: -255.500 [R] -to- -0.500 [R] -step- 1.000 mm [256 voxels]
A-to-P extent: -255.500 [A] -to- -0.500 [A] -step- 1.000 mm [256 voxels]
I-to-S extent: 0.500 [S] -to- 191.500 [S] -step- 1.000 mm [192 voxels]
2. 3dinfo hf01_run1+orig. |grep -e extent -e orient
++ 3dinfo: AFNI version=AFNI_2011_12_21_1014 (Nov 19 2014) [64-bit]
third (z) = Inferior-to-Superior [-orient RAI]
R-to-L extent: -97.098 [R] -to- 99.777 [L] -step- 3.125 mm [ 64 voxels]
A-to-P extent: -118.608 [A] -to- 78.267 [P] -step- 3.125 mm [ 64 voxels]
I-to-S extent: -5.548
-to- 92.452 [S] -step- 3.500 mm [ 29 voxels]
Thanks again,
Corrie
