External Email - Use Caution        

Hi all,
I noticed the following error message in a reconall-log concerning wm segmentation:

mri_segment -keep -mprage brain.mgz wm.seg.mgz...
...
ERROR: mri_segment-MRIcheckVolDims: volume1 height=336 != volume2 height=256.

I looked at resulting surfaces and can't find a cause for concern, should I be concerned? I presume the volumes in question are non-conforming, could someone explain what the issue may be.
Thanks in advance,
Kambiz
