Hi Francesca,

it means it couldn't find the corpus callosum. You can add the following to your recon-all command line:

-cc-xyz <X Y Z>

where <X Y Z> are the coordinates of the point in the callosum to be used for separating the two hemispheres.

cheers, Bruce

Hi there:

I am trying to lunch the stage1 on a set of IR-SPGRs and I keep having an error saying:

Mri_fill: could not find valid seed for the cc.

I am not sure how to interpret this.

Thanks,
