VipSplitBrain Failure

[Olivier_Colliot]

Hi

When processing the anatomical pipeline, we have the following problem with the Split Brain step:

Code: Select all

in Vip Split Brain 1 RuntimeError: System command exited with non null value : 111

In the log, we found the following information:

Code: Select all

erosion of size 4.000000 mm
dist:    4.0
cc(16928) highest point: x:83, y:170, z:67
cc(13819) highest point: x:72, y:172, z:68
cc(576) highest point: x:104, y:199, z:115
cc: 16928 points, back: 0%, right: 100%, left: 0%, cereb: 0%
cc: 13819 points, back: 35%, right: 20%, left: 0%, cereb: 44%
cc: 576 points, back: 0%, right: 99%, left: 0%, cereb: 0%
color choice (R=1,L=2,C=3) : 1 0 1 
--------------------Bad split-------------------
Perhaps CA, CP and InterHemispheric point are bad?
 (if you have not set it)
As an alternative, you can disable
 the use of the voronoi template (-T n)
-----Perhaps you can wait for the next one------
Can not find hemisphere seeds

When trying to disable the voronoi template, we still have the same error.

We have the same problem with either versions 3.0.1, 3.0.2 or 3.1

Also, the same problem occurs with about 75% of our database.

I could not find anything in our data that could explain this problem. The MRIs are acquired in sagittal. The GM/WM constrast is not great but should be sufficient.

Does anybody have an idea?

Thanks a lot
Olivier

Well, I am afraid the template used to guide the splitting procedure does not deal correctly
with sagittal images if you do not allow the importation to reformat the data into axial.
