Liat, Could you tell us the browser you are using? Because we have been using the fswiki without problems. ( and I can access fswiki from my home, hence we can rule out the case that fswiki is not available external to our center ) https://surfer.nmr.mgh.harvard.edu/fswiki and http://su

Have you looked at the brains? Is the one that takes a week correct, or does it have cerebellum or skull attached, or some other failure? cheers, Bruce On Tue, 10 Jun 2008, Marlisa Isom wrote: Hi All, We have 3 Mac Pros with Leopard which we use to process data (version 4). Two of them proc

Hi Tricia, each region grows into the white matter until a prespecified distance threshold is reached, so it's not quite each gyrus, particularly for the non-gyral parcellation units. You can visualize them in tkmedit to get a better idea. cheers, Bruce On Tue, 10 Jun 2008, Tricia Merkley wr

The algorithm is relatively simple. For each white matter voxel, it finds the closest surface point. If that point is further than 5 mm away, then it is labled as "unsegmented white matter". If it is closer, then it is given the label of the cortical parcellation. doug Tricia Merkley wrote:

Hi All, We have 3 Mac Pros with Leopard which we use to process data (version 4). Two of them process a brain in 30-36 hours, but one takes a week to process ONE brain if not more. While the processors are slightly different (3GHz vs 2.6), not amazingly so. This is seemingly the only difference. D

Hi, I just have a quick question regarding the white matter regional volumes as shown in the wmparc.stats file.  How are the white matter regions grown inward from the cortical parcellation?  Does each labeled region include only the white matter within the specified gyrus, or does it extend fu

Martin, One thing to try is to make sure that your volumes look ok. There is a tutorial here: http://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/OutputData You don't need to download the tutorial data to follow it, just substitute the subject 'bert' which is distributed in the freesurfer/subjec
