Hello again mailing list,

Can anyone address the possible cause of the medial surface problem shown below (overestimating of rh medial surface, shows up in the long image and not the tp or base images). Forgot to mention that I am using freesurfer v5.3 with an updated mris_make_surfaces binary (sourced from the development version at ftp://surfer.nmr.mgh.harvard.edu//pub/dist/freesurfer/dev_binaries/centos6_x86_64/ ).

Here is the image again:

Hi mailing list,

I am currently processing a longitudinal image and have come across a problem at the medial surface in the long image (step 3). As you can see in the attached image, the rh medial surface has been significantly overestimated and extends into the lh surface. This error showed up only in only 1 of the 2 long images for this subject, and both the time-point images and the base are perfectly fine. Do you know why this is happening?
