Dear All,
I have some T1 images I have normalised. The normalised images look sensible with good registration. However, when I segment the images, I appear to get an underestimation of grey matter and an excess of CSF. This particularly affects medial frontal regions and the anterior cingulate, where in comparison to the normalised images, the interhemispheric fissure seems far larger in the segmented images. Is it possible to "tweak" the segmentation?
Many thanks
Xavier
