Hello freesurfers!
My resting state data is in fsaverage5 space. mri_info gives dimensions of 3414
x 1 x 3 x 120 and voxelsize 1x1x1.
I do the group analysis and mri_glmfit creates a sig.mgh file that is has those
same dimensions and results look good. Then I say:
mri_glmfit-sim --glmdir
Dear Freesurfers!
I would like have my fMRI runs in the native T1 volume space and do the first
level analyses there. I can only find -self flag for surface based analyses in
preproc-sess. What would be there recommended way to do the analyses in the T1
volume space? This is 7T data and I’d
Dear Freesurfers,
When I run freesurfer 6.0 recon-all -hippocampal-subfields-T1 command to
segment an MNI152 template, the resulting segmentation of left hippocampus got
flipped in left-right dimension. Otherwise the right hippocampus and other
subcortical segmentations in the aseg-file look
Hi all,
I’m trying to run preproc-sess using symbolic links in my SUBJECTS_DIR but the
program exists with error message: could not find session .
Symbolic links work fine when I run recon-all for instance.
Suggestion for a fix would be greatly appreaciated.
Cheers!

Dear freesurfers,
I have data collected here at the martinos using the Siemens ep2d_PASL
sequence. I run the command "rcbf-prep —s subject —rcbf asl.nii —o tesfolder"
or something like that. The resulting rcbf.nii looks good, but the values are
negative? Is this just a matter of tag and ref
Hi everyone,
Is there a template of the hippocampal subfields in some average space?

Dear Freesurfer experts,
I ran recon-all on launchpad using /usr/local/freesurfer/stable6/bin/recon-all.
This command worked nicely, but part of the occipital cortex was missing and I
therefore ran the following command ( both in freesurfer6 ):
recon-all -skullstrip -wsthresh 35 -clean-bm
