Tracula FS 6 vs FS 7.1.1
by Alexopoulos, Dimitrios 17 Sep '20

17 Sep '20

External Email - Use Caution Are there any differences in usage /outputs from Tracula in FS 6 vs FS 7.1.1? Specifically as it relates to the customized dmrirc config file? The wiki mentions a beta version of Tracula in FS. 7.2. Will the general usage be similar to 6/7.1.1?

display P-values for T-test on differences in mean FA/MD/… between groups
by Zeng, Qi 17 Sep '20

17 Sep '20

External Email - Use Caution Hi, In Tracula Wiki, there is a slice of displaying P-values for T-test on differences in mean FA/MD/… between groups following this link and sample plot attached below. https://ftp.nmr.mgh.harvard.edu/pub/docs/TraculaNov2013/tracula.workshop.ii… . I want to know what is the command for this and is there a useful link to demonstrate the process? Thank you so much! Best, Qi --

outputs from step of trac- all prep
by Zeng, Qi 17 Sep '20

External Email - Use Caution Hi, Where is the nifti output stored from running trac-all preprocess? Is it dmri/dwi.nii.gz? Is there an additional step segment this nifti file into the grey matter and white matter for later tensor-fitting? Best, Qi

Re: [Freesurfer] Hippocampal segmentation -quality check

Hi Liz, I cannot say for sure without seeing the posteriors, but that totally looks like it is part of the alveus – which we leave out of the hippo subfield segmentation. Cheers, /Eugenio Juan Eugenio Iglesias Senior research fellow CMIC (UCL), MGH (HMS) and CSAIL (MIT) http://www.jeiglesias.com From: <freesurfer-bounces(a)nmr.mgh.harvard.edu> on behalf of Lizbeth Ayoub <lizbeth.ayoub(a)utoronto.ca> Reply-To: Freesurfer support list <freesurfer(a)nmr.mgh.harvard.edu> Date: Wednesday, September 16, 2020 at 23:41 To: "freesurfer(a)nmr.mgh.harvard.edu" <freesurfer(a)nmr.mgh.harvard.edu> Subject: [Freesurfer] Hippocampal segmentation -quality check External Email - Use Caution Hi everyone, I am in the process of checking my hippocampal segmentations. I am finding that the hippocampal mask is often underestimating certain grey matter areas perhaps pertaining to the hippocampus? For example, the area pointed by the red arrow, here below, was initially covered by the apart + aseg hippocampal mask. Would the FS voxel space mask of the hippocampus pass quality check or would you say that a part of the hippocampal grey matter would be missing ? Thank you for your helpful insight, Liz Liz[cid:image001.png@01D68C86.C1F12140]

Hippocampal and amygdala subregions using earlier freesurfer version segmentations
by Keith Harenski 16 Sep '20

16 Sep '20

External Email - Use Caution Hello, I just wanted to verify that using segmentations from earlier freesurfer versions (5.3) are valid as input into the subsequent further segmentation into the hippocampal and amygdala subregions. I understand the input volumes will vary based on version.

Freeview 7.1.1 won't start on Mac: segmentation fault
by Alex White 16 Sep '20

16 Sep '20

External Email - Use Caution Hello again dear Freesurfer experts I recently updated to v7.1.1, in order to get the latest version of Freeview. I’m using Mac OS 10.15.6. Freeview seems to start once each time I boot up my machine, but if I quite it, I can’t re-start it again (until re-booting the machine). In the terminal I get an error like this: /Applications/freesurfer/7.1.1/bin/freeview: line 2: 6667 Segmentation fault: 11 $FREESURFER_HOME/Freeview.app/Contents/MacOS/freeview "$@“ The number after “line 2” isn’t always the same. If I try to start Freeview by clicking on its icon, I get a window that says, “freeview quit unexpectedly.” I can send you the full crash report if you like. Any advice? Thanks again, Alex White

External Email - Use Caution Hello Alex, If you want to use the Finder to directly launch the freeview *application*, then I would double click on an application bundle (named *.app or in this case Freeview.app)  which is directly under /Applications/freesurfer/7.1.1.  You can drag the application icon into your dock to run Freeview from there. The shell script under /Applications/freesurfer/7.1.1/bin is usually run from the command line by typing “freeview” in a terminal window after you have setup your shell environment (set FREESURFER_HOME and source the freesurfer setup script which sets/modifies PATH, etc.).  With everything set in the terminal window shell environment, then running the freeview script from the command line will launch the Freeview.app - see below.. - R. Open a terminal window and at the prompt type “bash”, then do, Mac:~> export FREESURFER_HOME=/Applications/freesurfer/7.1.1 Mac:~> source $FREESURFER_HOME/SetUpFreeSurfer.sh-------- freesurfer-darwin-macOS-7.1.1-20200726-8b40551 --------Setting up environment for FreeSurfer/FS-FAST (and FSL)FREESURFER_HOME   /Applications/freesurfer/7.1.1FSFAST_HOME       /Applications/freesurfer/7.1.1/fsfastFSF_OUTPUT_FORMAT nii.gzSUBJECTS_DIR      /Applications/freesurfer/7.1.1/subjectsMNI_DIR           /Applications/freesurfer/7.1.1/mni Mac:~> which freeview/Applications/freesurfer/7.1.1/bin/freeview ....then the freeview application should launch when you type ...
