The file 'lh.area' contains 126850 elements. The file 'lh.area.pial'
contains 126355 elements.
You cannot add them together since they have different sizes.

Were these oblique acquisitions?
By default, dcm2nii and MRIConvert rotate the bvecs according to the
orientation info for oblique acquisitions, whereas it sounds like
mri_convert might not be doing that.

The 4th handles any translation. The 3x3 handles rotation and any scale.

There may be some obliquity (from 3dinfo of the created nifti file):

Just my two cents:
I think the age should be mean-centered; otherwise, the meaning of the other
variables need to be interpreted as age = 0 (rather than mean age = 0).
In general, I believe in qdec or mri_glmfit, the effects of Class variable are
interpreted as 0 on the continuous/nuisance vari
