Hi Rick,

3dinfo output is the following:

Dataset File: s03-2.3danat_flip_brain.nii.gz
Identifier Code: NII_qREKipwQuWPcK1unZE4zbQ Creation Date: Fri Sep 12 14:28:13 2008
Dataset Type: Anat Bucket (-abuc)
Byte Order: LSB_FIRST {assumed} [this CPU native = LSB_FIRST]

Geometry String: "MATRIX(1,0,0,-80.653,0,-0.9375,0,126.9063,0,0,0.9375,-106.2815):160,256,256"
Data Axes Tilt: Plumb
Data Axes Orientation:
first (x) = Right-to-Left
second (y) = Posterior-to-Anterior
third (z) = Inferior-to-Superior [-orient RPI]
R-to-L extent: -80.653 [R] -to- 78.347 [L] -step- 1.000 mm [160 voxels]

I-to-S extent: -106.282 -to- 132.781 [S] -step- 0.938 mm [256 voxels]
Number of values stored at each pixel = 1
-- At sub-brick #0 '?' datum type is float: 0 to 3803.78

I cannot Taliarach this dataset:
ERROR: Can't write HEADER only for NIfTI-1 file: ./s03-2.3danat_flip_brain.nii.gz

I am assuming that I have a version of NIfTI that cannot be written to by AFNI?

Sincerely,

Anastasia
