[Freesurfer] FSFAST registration

External Email - Use Caution Dear FS experts, I’m processing the task-related fMRI using FS-FAST. I check the quality assurance and modified some subjects’ registration file(named new one as “register_manual.lta”). Then I do the first level analysis and gr

[Freesurfer] ROI Analysis in a given label with Functional Constraint in FSFAST

External Email - Use Caution FS experts,Commonly, I can use mri_vol2vol -> mri_segstats to extract anatomical ROI from aparc or aseg template.However, now I want to extract the average percent signal change in the hV5+/MT by constrained  positive functiona

[Freesurfer] Difference bewteen beta and ces in FS-FAST

External Email - Use Caution Dear FS experts, Hi!I have a very basic question about GLM model in FS-FAST.After GLM analysis, there is a beta.nii under the analysis/ directory and a ces.nii under each contrast/ directory. In the tutorial,  beta.nii is the regression coef
