Steps for Correcting Dura Using Multi-echo MPRAGE
by KEITH JONES 17 Jul '24

17 Jul '24

External Email - Use Caution Hi everyone, I am running Freesurfer on some multi-echo MPRAGE data in order to extract cortical thickness. I would like to use the multi-echo data to improve the surfaces, and I found example code to do that on a previous post. However, it's not clear to me if there are any steps after this. Do I need to rerun any part of recon-all in order to use these newly created surfaces for cortical parcellation and thickness extraction? My exact code is below: Step 1: Run recon-all recon-all -subject ${SUBJECT} -i {T1RMS} -sd ${OUTPUT} -mprage -3T -T2 ${T2} -T2pial -hires -threads 16 -all Step 2: Adjusting dura mris_make_surfaces -dura memprage_echo%d.mgz 4 -sdir ${OUTPUT} ${SUBJECT} ${HEMI} Step 3: Rerun part of recon-all to use the new surfaces? Step 4: Extract data with aparcstats2table Thanks for the help! Sincerely, Keith Jones

mri_gtmpvc RBV - cannot find file from a custom subject directory
by Sneha Pandya 17 Jul '24

17 Jul '24

External Email - Use Caution Dear team, I am running mri_gtmpvc using RBV correction, however when I do so I get an error message saying it cannot find $SUBJECTS_DIR/$subject_id/mri/orig.mgz needed for RBV. Our Freesurfer outputs are nested as $subject_id/MPRAGE/Freesurfer/mri/orig.mgz. I tried mri_gtmpvc with "--sd" flag as well, still same error as when I set "--sd $subject_id/MPRAGE/Freesurfer" it tries to find the file as $subject_id/MPRAGE/Freesurfer/$subject_id/mri/orig.mgz. One way I can avoid doing this is by creating a soft link with the expected path, however if there is a better way to do so that would be great. Thank you, Sneha

Functional connectivity: sig.nii.gz values seem off
by Doll, Laura 12 Jul '24

12 Jul '24

External Email - Use Caution Hi, I ran a functional connectivity analysis according to the walkthrough in the Freesurfer Wiki. After the group analysis (with mri_glmfit using ces and cesvar), I plotted the results (sig.nii.gz of the GLM) with freeview, but the distribution seems off. I'll attach a screenshot, but in case someone cannot access it: There are only few negative data points, the majority seems to be in two (!) approx. gaussian distributions centered at ~5 (the smaller one) and ~8, so most points have values between 5 and 10. Running an FDR correction suggested that the threshold should be 1.3 Because the seems highly unlikely, I search the mailing list archive and found out about the bug in the functional connectivity analysis. Therefore, I repeated the group analysis with the pcc instead of the ces, but that didn't really change anything. Side note/question here: There is no variance corresponding to cesvar I could use in that case, right? Any suggestions on what could've gone wrong? Here are the exact steps I used: # Create nuisance variables for white matter: fcseed-config -wm -fcname wm.dat -fsd bold -pca -cfg wm.config fcseed-sess -sf Part3HR -cfg wm.config # Create nuisance variables for ventricles + CSF: fcseed-config -vcsf -fcname vcsf.dat -fsd bold -pca -cfg vcsf.config fcseed-sess -sf Part3HR -cfg vcsf.config # Auditory cortex ################## # configure parameters fcseed-config -roi AC-rh -fcname AC-rh.dat -fsd bold -mean -cfg AC-rh.config # create FC seeds fcseed-sess -sf Part3HR -cfg AC-rh.config # FC analysis mkanalysis-sess -analysis fc.AC.surf.rh -surface fsaverage rh -fwhm 5 -notask -taskreg AC-rh.dat 1 -nuisreg vcsf.dat 5 -nuisreg wm.dat 5 -mcextreg -polyfit 5 -nskip 4 -fsd bold -TR 2 -per-run selxavg3-sess -sf Part3HR -a fc.AC.surf.rh isxconcat-sess -sf Part3HR -analysis fc.AC.surf.rh -o AverageFC_AC -all-contrasts -map pcc mri_glmfit --y ./AverageFC_AC/fc.AC.surf.rh/AC-rh/pcc.nii.gz \ --osgm \ --surface fsaverage rh \ --glmdir ./AverageFC_AC/fc.AC.surf.rh/GLM_AC-rh \ --save-eres \ --nii.gz I'd appreciate any input.

Licence for using Freesurfer-generated images in a book?
by ALARIO Francois 12 Jul '24

12 Jul '24

External Email - Use Caution Hello I am considering using freesurfer-generated images not in a scientific paper but in a popular science book (commercial). What is the preferred course of action, license-wise, for this specific purpose? Can I include images of fsaverage with Desikan atlas parcellations, or should I avoid using fsaverage and use instead images I have acquired? The general license is worded in terms of “Software”, but said figures would not appear to laypeople to be “Software” May I skip the words "All or portions of this licensed product (such portions are the "Software") have been obtained under license from The General Hospital Corporation and are subject to the following terms and conditions:" and more plainly acknowledge that the images were created with Freesurfer by citing ''Cortical reconstruction and volumetric segmentation was performed with the Freesurfer image analysis suite, which is documented and freely available for download online (<http://surfer.nmr.mgh.harvard.edu/>)'', along with one of the papers (which one)? The book is in French the recommended option would be translated to French. Any advice would be appreciated. Kind regards Xavier -- Xavier ALARIO + 33 4 13 55 09 72 https://cv.hal.science/f-xavier-alario https://crpn.univ-amu.fr/fr/annuaire/alario-xavier

Unknown recon-all error - ERROR: reading ../surf/autodet.gw.stats.lh.dat

External Email - Use Caution Hello there! I'm hoping that someone can resolve this issue which I'm having. To me it seems that the pipeline is looking for ../surf/autodet.gw.stats.lh.dat, and I can confirm that it does not exist. Is there a quick solution?
