Segmentation pipeline

Post by Sylvain »

Dear brainvisers,

I am using version 3.1.0 of the segmentation pipeline on a coronal T1 volume. I am getting warning and error messages of the following kind:

-----------------------------
! VIP Warning:
Strange: gap of more than 5 points along this trajectory (use smaller scale step)
------------------------------
Singularity steming from iteration 341 and localization 24
lost at iteration 0
------------------------------
!! VIP Error:
Not enough memory...
------------------------------
------------------------------
!! VIP Error:
Execution aborted in function '(Vip_alloc.c)VipRealloc'.
------------------------------
------------------------------
!! VIP Error:
Memory pb in realloc
------------------------------
------------------------------
!! VIP Error:
Execution aborted in function 'VipDwindle3DBucket_S16BIT'.
------------------------------
------------------------------
! VIP Warning:
Empty volume in VipGet3DConnex
------------------------------

and then it crashes during the SplitMask process (although the brain mask is looking good). Any piece of advice at this point, please?

thank you,

Sylvain.

Thank you, Jeff.

The default was set to 'auto'; I changed it to '8' and it worked just fine.

thanks a million!
