extra cerebral CSF
by Jared Nielsen 23 Aug '19

23 Aug '19

External Email - Use Caution I've seen some previous posts about a measure of extra cerebral CSF coming in the future. Is the measure now available, or is it still in the works? If it's still in the works, can an ETA be provided? Thanks, Jared

TRACULA - OrientLAS issue for a subject
by Daniel Callow 23 Aug '19

23 Aug '19

External Email - Use Caution For reference, I think the issue had to do with the orientation of these two subjects. I added tome code to use 3dwarp -deoblique to the dwi_orig.nii.gz and then ran orientLAS and it worked this time. The only thing I am unsure about is if this will nulify the bvals and bvecs I have and ruin later preprocessing steps? This is the only solution to the problem I have found thus far though. *Daniel Callow* *PhD Student, Neuroscience and Cognitive Science* Exercise for Brain Health Lab University of Maryland, College Park *ddcc2442(a)gmail.com <ddcc2442(a)gmail.com>* 443-254-6298

Dear Freesurfer experts I am doing recon-all on one of my subjects and it seems that it's stuck for days and not going through. I even re-run it and it's still stuck at the same spot as before. I attached the log file and here is my command: recon-all -all -s $subj -i /$subj/anat/$run/mT1v2.nii -expert expertopts/expert.opts -hires -mail zn025 -parallel I appreciate any help. Thanks Mona Zahra (Mona) Nasiriavanaki Postdoctoral Research Fellow Martinos Center for Biomedical Imaging Massachusetts General Hospital 149 13th Street, 149-2615 Charlestown, MA, USA, 02129

Help with using family as random effect in sibling study
by Hopkinson, Casey E 23 Aug '19

23 Aug '19

Hello! I am trying to generate significance maps for a paired-difference analysis of cortical thickness using multiple pairs of siblings, and was wondering if there is a way to incorporate the family ID as a random effect/covariate in Freesurfer. Is it possible for the family ID for each sibling pair to be used as a categorical/discrete variable to then see the effect of family on cortical thickness in addition to the main effects we are looking at? Any guidance would be greatly appreciated!

Converting surface coordinates to MNI coordinates
by Avi Gharehgazlou 23 Aug '19

23 Aug '19

External Email - Use Caution Hi, I am conducting a meta-analysis on papers that have looked at local gyrification index (lGI) in Autism Spectrum Disorder (ASD) relative to typically developing (TD) peers. All lGI papers have used the FreeSurfer software and have reported x,y,z coordinates for their significant clusters (in which lGI in ASD is different from TD). Please help me with the below 2 questions: 1. My understanding is that these coordinates reported in lGI papers are "surface coordinates" (of fsaverage). Is this correct? 2. How can I convert these x,y,z surface coordinates to MNI space coordinates? I'd really appreciate your reply, Thanks so much, Avi

Gender and age based reconstruction
by Carissa Liana Grijalva 23 Aug '19

23 Aug '19

External Email - Use Caution Hello FreeSurfer Support, I reached out the other day about if there was a way to specify the data is from a specific gender or age during the recon all code, such as a tag at the end. I was told that there is not way to tell recon-all about demographics/subject meta data, and not to worry about this during recon-all, but instead add age and gender as covariates in the model later. Does this mean FreeSurfer automatically finds the right regions regardless of age or gender? Does this work based on gray/white matter thresholds or something similar, so regardless of the demographics of the brain, it find the right regions? Thank you for your time.

mris_convert segmentation fault on R hemisphere aparc.a2009s only?
by Damion V Demeter 22 Aug '19

External Email - Use Caution Hi Bruce, My apologizes, I just saw this reply because I didn't realize I had the list on digest mode. I would very much appreciate your help!

Hello, I am trying to freeze the development freesurfer version for today and I am denied access to copy the following files: /usr/local/freesurfer/dev.backup/average/mult-comp-cor/fsaverage/rh/cortex/mask.mgh /usr/local/freesurfer/dev.backup/average/mult-comp-cor/fsaverage/lh/cortex/mask.mgh /usr/local/freesurfer/dev.backup/subjects/fsaverage6 /usr/local/freesurfer/dev.backup/subjects/fsaverage/scripts/fix-surf7.log /usr/local/freesurfer/dev.backup/subjects/fsaverage3 /usr/local/freesurfer/dev.backup/subjects/fsaverage_sym/scripts/fix-surf7.log /usr/local/freesurfer/dev.backup/subjects/fsaverage4 Are they instrumental? Are they the same as stable6? How can I have access to these? (I am in the Martinos cluster) Thank you, Aura M.
