Hi Doug,
As a post-mortem to this thread, in the process of going to "tweak" the
wm.mgz as you suggested, I noticed that there were actually some
substantial errors in the surfaces in the calcarine, presumably due to
topology correction gone astray. So, whether or not that precipitated
the probl
mris_euler_number surf/lh.white
euler # = v-e+f = 2g-2: 166103 - 498303 + 332202 = 2 --> 0 holes
F =2V-4: 332202 = 332206-4 (0)
2E=3F:996606 = 996606 (0)
total defect index = 0
mris_euler_number surf/rh.white
euler # = v-e+f = 2g-2: 167114 - 501336 + 334224 = 2 --
what is the euler number for the white surface for this subject
(mris_euler_number)?

Hi Mike, I *think* I've found the problem with this subject. The way
that the volume inside the white surface is computed is to create a
high-res volume (.25mm iso), then create a shell based on the
intersection of the faces with the volume. The outside of the shell is
"flooded", the result is
Hi Mike, can you upload the subject and I'll take a look?

Hello,
Anyone have a chance to look at this? Should we just forget about
trying to get an accurate lhCorticalWhiteMatterVol value for this
subject?
thanks,

Hi guys,
We have a subject processed with FS v5.1 in which
lhCorticalWhiteMatterVol in aseg.stats is much too low -- only 33781
mm^3. From what I see, the aseg.mgz looks fine. 'mris_volume lh.white'
returns 287261 and running mri_segstats without the --excl-ctxgmwm
option returns a Left-Cerebra
