Re: [Freesurfer] mri_glmfit correction across lobes

What is h.all.suvr.sm05.proj0.5.nii.gz? Where did it come from? The name looks like it might be a voxel-wise map, but you say something about ROIs. mri_glmfit does not correct for multiple comparisons. For ROI-based analyses, you can use bonferroni or FDR. For maps you can use mri_glmfit-sim.

[Freesurfer] dcmunpack behavior with scouts

2023-04-05 Thread Proulx, Jean Sebastien
Dear Freesurfer Team, The help of dcmunpack says it will ignore scout scans. Is there perhaps a hidden flag to avoid that behavior? We are running multiple scouts throughout a session to combat head motion. Getting those images along the rest would allow visualizing that motion offline.
