External Email - Use Caution Hi Douglas, Thanks for your reply. We used different tracers for diagnosis of AD or other neurodegenerative diseases, including PIB, FDG, Flutemetamol and TAU. If an SUV analysis is used, is it done by mri_gtmpvc? Is there any subsequent analysis

[Freesurfer] Using orig.mgz or T1.mgz as input to recon-all

External Email - Use Caution Hello FreeSurfer Developers, I am attempting to run recon-all on a group of subjects. We no longer have the raw T1s. Instead, we have their orig.mgz and T1.mgz files from a previous run of freesurfer. We wish to rerun recon-all using their orig.mgz or

External Email - Use Caution Dear FreeSurfer Experts, I'm currently working on mapping cortical morphometric measurements from each individual in the HCP dataset to the fsaverage space. I have noticed that both the mris_preproc and mri_surf2surf commands can achieve this
