[Freesurfer] mri_glmfit-sim on fsaverage5
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 /autofs/space/bee_001/users/Lauri/test10.nosm.group/lh.surf.avg.rh.204 --3spaces --sim mc-z 1 1.3 mc_1.3_3space --sim-sign abs —overwrite And I get an error message saying dimension mismatch between input volume and seg. below is the tail of the message.

[Freesurfer] How to analyze fMRI in native volume space
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 like to use the individual segmentations as ROIs. Thank you so much!

[Freesurfer] Hippocampal segmentation flips on the left side
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 fine. I encountered a similar problem when I tried to segment a T1 acquired at 7T. I run the command both locally and then on launchpad. Would you know how to fix this? Thanks so much for your advice!

[Freesurfer] preproc-sess with symbolic links
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!

[Freesurfer] ASL with rcbf-prep
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 images being in a wrong order and can I just fix it by removing the first image (after the M0)? Or is it more complicated?

[Freesurfer] Freesurfer 6 exits with errors after recon edits on skullstrip
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 -no-wsgcaatlas -s atib This took care of the brain mask problem that I had with the previous recon. So I then ran on launchpad: recon-all -s atib -autorecon2 -autorecon3 -hippocampal-subfields-T1' The last command exits with errors. Please find the log-files attached. Thank you for your help!
