Hi Knut
can you check the accuracy of the talairach xform? And what version are you using? Bruce On Tue, 25 Sep 2012, Knut J Bjuland wrote:
Hi, I have calculated relative volume by dividing each volume by the intracranial volume and multiply it with 100. When I add the relative volume of total gray matter, cortical white matter, lateral ventricle, 3rd centricle, 4th ventricle and ventral DC, I get 82-86 %. Can this be caused by the fact that the intracranial volume is much larger than the brain? In which way can motion correction affect volume if I have series where some subjects have to dicom and other just have one dicom serie?
