There's no attribute IJK_TO_DICOM_REAL for this dataset.
When I run 3dinfo, I get
"Data Axes Tilt: Unspecified, assumed plumb"
which AFAICT occurs only in thd_info.c, and happens when
"ISVALID_MAT44(dset->daxes->ijk_to_dicom_real)"
is false (which is consistent with not having such an attribute).
My guess as to what's going on: the dataset was originally processed with an older version of AFNI, old enough that the IJK_TO_DICOM_REAL attribute wasn't used at the time (just a hunch). Some/most of the oblique stuff was added in Dec 2007. It can't find the attribute so issues a warning.
