When I start the Cortical Surface Extraction Sequence using the GUI, the process always stops at topology correction during fixing topological defects of size 21, no matter which nii-file I use, and the Programme has to be closed. In the BrainSuite Log it only says ‘Too many edges in table’.
I use BrainSuite 15c with Windows 7.
Does anybody know what the reason for this is?
Thank you very much for your help!
Could you try loading up the *pvc.label.nii.gz (label volume of tissue types) file superimposed over your brain image? (Load either the unprocessed brain image or the bias field corrected (*bfc.nii.gz image) as Volume and load *pvc.label.nii.gz file as Label). From here, you can visually check the quality of the tissue segmentation. As you move your cursor around in the images, the bottom bar of your window will tell you which tissue type it has been labeled.
If your image has been poorly segmented, you may want to try editing your brain mask (Skull Stripping) or bias field correction (Nonuniformity Correction) parameters. I hope this helps!
