Dear Nima, As of today, there is no longitudinal version of recon-all-clinical. It’s a bit tricky to adapt the standard longitudinal pipeline in FreeSurfer to scans with thick slices due to the anisotropy of the images, and also due to the deep learning bits of the pipeline. But you can of cours

The 5th vent, non-wm-hypos, left and right vessel are not worrisome. The left and right cerebral cortex are probably just a few voxels that did not get recoded to the surface parcellation. The ento and parahippo  are probably a segmentation error (good that there are only a few of them:) On 2/

[Freesurfer] Issue with Voxel Size Mismatch in Samseg-Long Pipeline

Dear FreeSurfer Team, I am working with two timepoints for a subject and attempting to create a template for samseg-long using mri_robust_template. However, I encountered an error related to voxel size mismatch between the input images. Both timepoint images are T1W. The command I ran is: mri_r

You can merge them together with a combination of mris_annotation2label to split the annotation into different labels, then merge the labels you want with mri_mergelabels, then use mris_anatomical_stats to compute a stats file. Alternatively, and probably easier, is just to compute an average o

That is a harder problem. I'm not sure what is causing that bright spot. Artery? B0? The problem is that it is too bright and the algorithm says "hey, that's not gray matter" and does  not know what to do. You can edit the voxel intensities in the brainmask.finalsurfs.manedit to darken them so
