not really, it seems like there is a bug. If you can localize it to just one or a few subjects it would a lot easier to track down

Hi Bruce,
These are about 28 images. I have not tried fewer...do youthink there are some images with incorrect orientation in the cohort? That would show up in the other location in the average i think... sid. On Fri, Jan 23, 2009 at 8:46 AM, Bruce Fischl <fischl@nmr.mgh.harvard.edu

I don't think so. How many subjects? Have you tried fewer?

The surfaces look all right. It happens only to T1. It cant be a display
problem, can it?? sid.

that is strange. Do the surfaces look ok? How many subjects are you
averaging? Does this happen if you only average one or a few?

Hi everyone,
I am attaching a tiff file showing the tkmedit view ofthe average T1 that freesurfer created during make_average_subject. I am a bit concerned
about the cropping that is evident at the posterior aspect of the brain. The
individual T1's are complete and ok, so i am guessing that something went wrong during the transform of the individual brain during the process. Can anyone help me find out the problem ? The average surfaces also look all right. thanks, sid.
