      Hi everybody I am having a problem with size of the cortical surface results that it show smaller size than background MRI images. I tried to use different dicom to nifti converter but the result is the same. I dont know if any body had similar problem before, I appreciate your help and support.

      It look like this [/url]

      Hi Abujamea –

      It looks like a processing error happened earlier in the cortical surface extraction routine. Without seeing all of your output, my best guess is that the skull-stripping step didn’t remove a sufficient amount of the scalp/neck, which then resulted in a misclassification of GM during the tissue classification step.

      Can you step through the processing steps for cortical extraction and see where if it failed there?

      thanks,
      David Shattuck

        Thank you David you are right, I did skull-stripping using FSL and then use Brainsuite for the rest of processing and it works perfect.
