Re: [Freesurfer] mis-registration question

Can you send me your project folder and SUBJECTS_DIR?

I have a follow up question about mis-registration and I appreciate if you could please reply. I am having trouble fixing the registration for one of my subjects in highres scan. The tkregister-sess values looked bad (around 0.8). So I checked the registration with tkregister2 and it looked off too. I ran this command: "register-sess -s $subj -per-run -delete-dat -dof 6 -fsd bold4 -init-header -bbr-xopts bbr.xopts -d $all_subjects", with --brute1max 20 --brute1delta 4 ! which took a long while to finish! but still the registration is off. Could you please help me with that?

Thanks MOna

Can you send a pointer to the data so I can have a look? Include the folder were you run tkregister-sess from as well as the $SUBJECTS_DIR

Dear Freesurfers

Hi

I have a subject that the registration is not done correctly in two runs (run 12 and run 15) .

The tkregister-sess values for this subject is shown below.

Subject 1 10 0.2628 Subject 1 11 0.3038 Subject 1 12 0.7639 Subject 1 13 0.3364 Subject 1 14 0.3346 Subject 1 15 0.9361 Subject 1 16 0.2584 Subject 1 17 0.2488

I attached the screen shots from tkregister2 to this email. The functional data is only collected in a slab of parietal and occipital lobe.

I appreciate if you let me know how to fix them.

Thanks

Mona
