Cortical Thickness Using N30R83 Atlas
by Ryan Flores 15 Jun '18

15 Jun '18

External Email - Use Caution Hello all, I am hoping to obtain structural information (e.g., cortical thickness, surface area, and volume) based on the n30r83 (aka Hammersmith) atlas, which is in MNI space. The atlas differentiates between the hemispheres by using odd/even numbers in the labels. After looking through the archives I found a potential solution, which entails using the mri_vol2surf & mri_surf2surf commands. I’ve recon-ed the MNI brain to obtain the proper space; however, I’m unsure of how exactly to implement the commands and which flags are relevant. Any advice would be greatly appreciated. Thank you for your time. I look forward to hearing from you. Best, Ryan -- Ryan Flores Clinical Research Coordinator

Is amygdala nuclei segmentation possible in freesurfer version 5.3?
by Sally Grace 15 Jun '18

15 Jun '18

External Email - Use Caution Hi there, I wish to segment amygdala nuclei in Freesurfer Version 5.3, is it possible? I can find documentation only for Freesurfer version 6.0 here (https://surfer.nmr.mgh.harvard.edu/fswiki/HippocampalSubfieldsAndNucleiOfAm…) Can the scripts be adapted to Freesurfer v5.3? Thanks in advance, Sally.

So FS was not used to create the surface? If not, then you need to talk to the nipype people about how their gii interacts with your visualization tool. doug ps. Please post the FS list and not to us personally. thanks! On 06/14/2018 03:51 PM, Laura Jeyaseelan wrote: > > > Hi Douglas, > > Thanks for looking into this issue.

External Email - Use Caution Not sure what happened here, but running Freesurfer on Ubuntu and not getting this error when trying to view volumes: freeview -v \ mri/T1.mgz \ mri/brainmask.mgz \ mri/wm.mgz:visible=0 \ mri/aseg.mgz:colormap=lut:opacity=0.2 \ -f surf/lh.white:edgecolor=blue \ surf/rh.white:edgecolor=blue \ surf/rh.pial:edgecolor=red \ surf/lh.pial:edgecolor=red \ surf/rh.inflated:visible=0 \ surf/lh.inflated:visible=0 But it get the error: bash: mri/T1.mgz: Permission denied No idea why or how to fix this. I have also tried other subjects but same thing.

Hi All, Many of you might know Rahul personally from his time spent in Boston, at the Martinos Center and on Freesurfer (eg.: 'Desikan-Killiany' cortical atlas). The below is a great piece about his current struggles with ALS (and amazing work productivity): https://www.washingtonpost.com/news/national/wp/2018/06/13/feature/devastat… And here is a site where you can support his research: https://www.donorscure.org/project/project/?projectid=201b7e93-66d8-44a4-a1… Best, Lilla

mri_vol2surf projection
by Tom Vanasse 14 Jun '18

14 Jun '18

External Email - Use Caution Hello, I wanted to confirm that I properly performed the mri_vol2surf command. I'm interested in projecting a z-score image (in Talairach space) to an average surface (fsaverage5), using a mid-gray projection fraction. mri_vol2surf --src ICA_split0000.nii.gz --regheader fsaverage5 --hemi lh --o ICA_split0000_lh.nii --projfrac 0.5 My --src volume has array size (80 x 96 x 70) with 2mm isotropic voxels in Talairach space. The command ran without error, but I wanted to be sure it is indeed the correct approach. Thanks, Tom Vanasse Thomas J.

Is longitudinal lme analysis invalid when it doesn't converge?
by Knut J Bjuland 14 Jun '18

14 Jun '18

External Email - Use Caution Dear FreeSurfer experts I ran the lme scripts in FreeSurfer on FA-data (dMRI). The script doesn't crash but 70% of the models yield this message: "Algorithm does not converge after 50 iterations!!!" Does that mean the results (pvalues) are invalid? I would appreciate any input on this topic. Thank you! Best regards Knut Jørgen Bjuland

Re: [Freesurfer] Group Analysis Covariates
by Hua, Jessica 13 Jun '18

External Email - Use Caution Thank you for your response! Just to clarify: if my input is volume, does the cache.th20.abs.sig.y.ocn.dat contain the average unadjusted volume values for each participant in each significant cluster? Since the file I just mentioned contains the average values, I used mri_segstats to calculate total volume for the cluster. mri_segstats --i <pathway to rh.volume.Study.10.mgh> --seg cache.th20.abs.sig.ocn.mgh --excludeid 0 --sumwf ClusterVolumeValues.dat However, this just calculates the sum of the unadjusted values in the cluster. I guess my main question is, is there a way to extract or calculate the adjusted values for each participant in each cluster after accounting for covariates (age, sex, and ICV)? --- Jessica ________________________________ From: freesurfer-bounces(a)nmr.mgh.harvard.edu <freesurfer-bounces(a)nmr.mgh.harvard.edu> on behalf of freesurfer-request(a)nmr.mgh.harvard.edu <freesurfer-request(a)nmr.mgh.harvard.edu> Sent: Wednesday, June 13, 2018 11:00 AM To: freesurfer(a)nmr.mgh.harvard.edu Subject: Freesurfer Digest, Vol 172, Issue 21 Send Freesurfer mailing list submissions to freesurfer(a)nmr.mgh.harvard.edu To subscribe or unsubscribe via the World Wide Web, visit https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer or, via email, send a message with subject or body 'help' to freesurfer-request(a)nmr.mgh.harvard.edu You can reach the person managing the list at freesurfer-owner(a)nmr.mgh.harvard.edu When replying, please edit your Subject line so it is more specific than "Re: Contents of Freesurfer digest..."

When I look at the build timestamp on our stable 5.3 version of mri_convert I see it is from 5/2013. So the version that you listed is about 1 year newer than the 5.3 release I can see. It is possible that someone downloaded a daily/dev build of freesurfer at that time. You might want to consider running the latest 6.0 release of Freesurfer (released in January 2017), which should be fine on CentOS 7. It can be downloaded from, https://surfer.nmr.mgh.harvard.edu/fswiki/DownloadAndInstall I also suggest that you start out in a default/clean shell, set FREESURFER_HOME, and then source the setup script for linux, You can see the instructions on that same web page under ?Setup and Configuration?. The setup steps should work for version 5 or 6. - rob On Jun 12, 2018, at 2:43 PM, Aaron Tanenbaum <aaron.b.tanenbaum(a)gmail.com<mailto:aaron.b.tanenbaum@gmail.com>> wrote: External Email - Use Caution I checked my system is not encrypted.
