Hello,

We made changes to the aseg.mgz in the caudate, nucleus accumbens and ventricular region using Freeview. We are interested in getting the caudate volume. We used the following recon options in FreeSurfer v5.1.0: -autorecon2 –noaseg –autorecon3

Out of the 60 subjects that we ran, 4 exited with errors. I have provided the recon-all.log files.

(1)

Correction of the Topology

Finding true center and radius of Spherical Surface...done

Surface centered at (0,0,0) with radius 100.0 in 11 iterations

mhtVoxelList_Add(204, 160, 213, 229294): complete list too big!

(2)

CORRECTING DEFECT 6 (vertices=43037, convex hull=2066)

Segmentation fault

(3)

mri_fill: could not find pons

find_cutting_plane:seed point not in structure! Searching neighborhood..

(4)

CORRECTING DEFECT 0 (vertices=96569, convex hull=3716)

Excessive topologic defect encountered: could not allocate 980957071 edges for retessellation

Cannot allocate memory

Any help is greatly appreciated!

Thanks,

Jaiashre.
