Compute a binary mask of the brain from a bias corrected T1-weighted image
' The basic principles of this procedure are described in Ana Brain Mask from T1 MRI and Correction Brain Mask from T1 MRI. Moreover, the log files are full of information...'
In this low level access, you can tune some parameters to overcome difficult cases. If it is still a failure, your last hope is in using the commandline procedure, which gives access to much more parameters. An interesting alternative, however, is manual drawing, at least to clean up problematic areas... Semi-manual drawing may be especially wellcome when a lesion is disturbing the segmentation process.
