I ran 3drefit -oblique_recenter on the EPI starting image and something does not look right to me.
3dinfo ANA+orig.HEAD|grep extent (Modified EPI image - ran 3drefit)
++ 3dinfo: AFNI version=AFNI_22.0.09 (Feb 10 2022) [64-bit]
R-to-L extent: 82.500 [L] -to- 245.000 [L] -step- 2.500 mm [ 66 voxels]
A-to-P extent: -124.000 [A] -to- 94.000 [P] -step- 2.000 mm [110 voxels]

3dinfo orig/ANA+orig.HEAD |grep extent (Unmodified EPI image)
++ 3dinfo: AFNI version=AFNI_22.0.09 (Feb 10 2022) [64-bit]
R-to-L extent: -78.663 [R] -to- 83.837 [L] -step- 2.500 mm [ 66 voxels]
A-to-P extent: -126.300 [A] -to- 91.700 [P] -step- 2.000 mm [110 voxels]
I-to-S extent: -109.816 -to- 108.184 [S] -step- 2.000 mm [110 voxels]
The R-to-L extent in the "corrected" one looks incorrect to me.
