Hi, Thanks for the great FreeSurfer Course this past week. After running through Tracula and extracted the path stats (by voxel) across all subjects, can I apply mri_glmfit to test the group differences using the generated txt file that has all subject's diffusion meassure (e.g., FA) along particular spline voxels (the pathstats.byvoxel.txt, for example)?

Hi all,
We have run longitudinal analysis on two time points. The resulting longitudinal WM surface for both time points excludes large parts of the cortex. The cross sectional surfaces and the wm.mgz are correct. The base wm.mgz also seems to be fine, however, the base white and pial surfaces do not follow the wm volume properly.
We have rerun the longitudinal anlaysis (recon-all -long) according to the cheat sheet: 1. marking the base wm.mgz border with 255 voxel value (instead of 110) 2. adding control points to the base wm.mgz but it did not change the original result.
Any idea how this can be fixed? Thank you very much in advance!
Best, ruthi
