Hi Lena,

it's probably an incorrectly fixed topological defect. If you email me the wm.mgz and the lh.orig surface I'll take a look.

cheers, Bruce

Hi all

Please see the attached images ­ slices 108 to 111 What is happening at precentral / middle frontal white matter? How should I be correcting this? The wm slices as you can see have missing volumes. I cannot fill these spaces in wm surface ­ as there is no obvious white matter in the original surface. How should I go about correcting this?

Many thanks in anticipation Lena
