External Email - Use Caution Hi I'm using as seed in FS-FAST the outputs of segmentThalamicNuclei.sh. However when I run fcseed-config -segid 8103 -fcname L_AV.dat -fsd rest -mean -cfg mean.L_AV.config fcseed-sess -sf sessid -cfg mean.L_AV.config this error occurs: Voxel Volume is 36.3469 mm^3 Generating list of segmentation ids Found 1 segmentations Computing statistics for each segmentation Reporting on 0 segmentations Using PrintSegStat Computing spatial average of each frame ERROR: no voxels found in segmentation

Re: [Freesurfer] Reporting Cohen's D for a significant cluster
by Maksimovskiy, Arkadiy 20 Sep '18

20 Sep '18

Hi Bruce, Thank you so much for the tip and the quick response. For some reason, the position and Cohen’s D value do not change when I input the vertex and I think this might be due to an outdated Freeview version (2.0) that I am using. I attempted to load the new one from this link: https://surfer.nmr.mgh.harvard.edu/fswiki/UpdateFreeview But I am getting an error: The requested URL /pub/dist/freesurfer/freeview/freeview_osx.tar.gz was not found on this server. I was wondering if you have this file available at another location? Thanks again, arkadiy -- Arkadiy L.

Reporting Cohen's D for a significant cluster
by Maksimovskiy, Arkadiy 20 Sep '18

20 Sep '18

Dear Experts, I was requested to report the Cohen’s D value for a significant cluster, which resulted from a cortical thickness analysis. I was able to calculate it and open the resulting Cohen’s D mgh file in Freeview, together with the file, indicating a significant cluster. As expected, when I move the cursor within the significant cluster, Cohen’s D value changes with every vertex. I was wondering if you might have any recommendations for which of the Cohen’s D values to report, and how best to obtain that value? Thank you for your help, arkadiy -- Arkadiy L.

Troubles to determine the type of recon editing needed
by Diamond, Bram Ryder 20 Sep '18

20 Sep '18

Hi Matthieu, I've taken a look through the files you shared with us and I see the poor surfaces in the posterior right hemisphere you were referring to in your message. It looks like your subject has a combination of abnormally large ventricles and significant wm abnormalities, so I'm surprised FreeSurfer did as well as it did. As for the recon editing - I would recommend editing the wm.mgz to more accurately represent the wm from slice 84 to 39. You can take a look at the white matter edits tutorial<https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/WhiteMatterEditsV6.0> for details on how to do that. Then run the following command (substituting <subj_id> for your subject's id): recon-all -autorecon2-wm -autorecon3 -subjid <subj_id> The surface reconstruction may also benefit from labeling the right lateral ventricle in the wm.mgz (as an intensity of 250) - but I'm not certain since you didn't send us the surfaces for the left hemisphere. Before you do that, edit the wm.mgz as explained in the tutorial and tell us how that goes. All the best, Bram Bram R.

Error running recon-all
by Mark Wagshul 20 Sep '18

20 Sep '18

External Email - Use Caution Hi. I am getting the following error trying to run recon-all (with Version 6.0), it is failing while running the routine mri_nu_correct.mni: Can't locate MNI/Startup.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at /public/apps/freesurfer/6.0.0/mni/bin/nu_correct line 37. I am guessing that this has to do with the setup of the environment variables, but not sure what needs fixing. Any advice would be much appreciated, thanks.

freeview automated screenshots using color wheel scale & qt library issues
by Emil H.J. Nijhuis 20 Sep '18

20 Sep '18

External Email - Use Caution Hi, I am attempting to generate automated screenshots with freeview version 3.July 2018 and I noticed that when applying the color wheel option for a surface overlay the coloring would be wrongly applied and I would need to enter the configuration window to fix/refresh the overlay coloring. Is there any way to enforce a refresh for overlays using the command line? Also is there a way to save/load custom color scales with the command line? I tried to use the latest developmental freeview.bin, however it gives me the error: version 'qt_5' not found; for 4 existing qt libraries which are softlinked to a newer versions (qt 5.5) in my system. Do you have any advice to achieve automated screenshots with freeview? With kind regards, Emil Nijhuis

Any ideas would be greatly appreciated, thank you! ======== Toshiki Okadome

Step of coordinates transforming
by 薛倩雯 19 Sep '18

19 Sep '18

External Email - Use Caution Dear Freesurfer experts, I need to transform a bunch of MNI coordinates of fiber tracts to native space. I have already done the follow steps: (1)intra-subject registration (register the individual's low-b diffusion to T1images using bbregister ) (2)inter-subject registration (register the individual's T1 image to cvs_avg35_inMNI152 template) How can I transform the MNI coordinates back into the native space? Thanks!Qianwen

Re: [Freesurfer] Freesurfer 6.0 - Tracula - Segmentation fault
by Matthew Grecsek 19 Sep '18

19 Sep '18

External Email - Use Caution Yes, a part of the brain appears missing. See attached screenshot. I did not use a configuration file, I simply accepted all defaults and kicked off the process with -s and -i flags. ------------------------------------------------ Re: [Freesurfer] Freesurfer 6.0 - Tracula - Segmentation fault Yendiki, Anastasia Wed, 19 Sep 2018 09:02:47 -0700 Hi Matt – It looks like some sort of registration issue. When you display the FA map (dmri/dtifit_FA) and structural segmentation in diffusion space (label/diff/aparc+aseg), do they look fine? Is there any part of the brain that is cut off from any of the images? Also, can you attach your config file? Thanks! a.y
