Maybe your computer had some hardware related error that time. I would try
running Bedpostx again (though you should also check nodif_brain_mask to
ensure that nothing is missing in it either).
Peace,
Matt.

Subject: [FSL] Bedpostx doesn't process all slices
Dear experts,
I ran bedpostx on a data which consist of 91 slices. I examined the
resulting merged_ph<i>samples and merged_th<i>samples in fslview and this
data had only 40 slices. Data looked like having the slices 1-20 and 71-91,
that it, it seems that bedpostx had processed the first 20 and the last 20
slices, and missed a stack of 51 slices in the middle.
The only error message I could find was in bedpostx_preproc.sh.e9567 and it
said:
++ WARNING: nifti_read_buffer(/home/u3/hsantila/dti/data.nii.gz):
data bytes needed = 1805258
data bytes input = 857922
number missing = 947336 (set to 0)
However, the file data.nii.gz seemed to be ok (had all the slices etc.),
when I loaded it into fslview.
Has anyone ran into similar problems? What could this error message mean?
I will be grateful for all help
Hanne
