Thanks for your guidance. I already tried recon-all-clinical.sh; however, I was wondering why did this happen? Could it be related to resampling process or the orientation?

I resampled this MRI in 3D Slicer using B-Spline interpolation and then saved it as a mgz file. After running recon-all on this resampled file, I noticed that the right hemisphere’s segmentation and parcellation are flawed. Also, considering the age and health situation of this patient, i believe the WM hypointensities are overestimated in the left hemisphere. I am using the following version of FreeSurfer: freesurfer-macOS-darwin_x86_64-7.4.1-20230614-7eb8460. The command line was: recon-all -s 12th_recon_output -i input.mgz -all -parallel -openmp 12 I’ve attached the recon-all log file, a screenshot from Freeview to illustrate the issue, and mri_info file. I would greatly appreciate any guidance, troubleshooting advice, or suggestions on what might have gone wrong and how to correct this issue. Thank you in advance for your help!
