27 Jul '22

External Email - Use Caution Hello, I am a neuroimaging researcher and have been trying to install Freesurfer on a Windows OS using a Virtual Machine, following the instructions below: "Download and Run the Virtual Machine: Ubuntu 18.04.06 compressed image with the Freesurfer 7.2.0 release installed: FS_7_2_0_Ubuntu_18_04_06.ova.7z<https://secure-web.cisco.com/1PaZD_uN8-j2duK-8vB8-Bcab_yu4LfPOhhM0EQRGqACIp…> Right click on the <file name>.ova.7z file and see what options you have under the choices for "Open with". If your current archive program choices cannot open a 7zip file, then try installing one of the utilities listed below. You will be prompted for a pass code when the archive is successfully opened. If you do not have the pass code to open the image, then send an email to the Freesurfer help list to receive it." I do not have the passcode to open the image and therefore am emailing the freesurfer help list, please advise.

Group Analysis - FSGD and Contrast
by Boa Sorte Silva, Narlon 27 Jul '22

27 Jul '22

External Email - Use Caution Dear experts, I am conducting a group analysis and wanted to confirm that the set up below accurately addresses our research question. Thanks for your help, much appreciated! Background: * We have two groups (intervention vs control) and two timepoints (pre vs post) * Our data have already been processed and stacked with long_mris_slopes where pc1 is the measure of interest (post - pre). * Our covariates are sex (male vs female), age, and MMSE scores. * Thus, our model has 4 groups (2 factors/2 levels): * int_male * int_female * con_male * con_female * We’re using DODS * We’re running the analysis with mri_glmfit in the Longitudinal Two Stage Model As such, we want test whether there are greater changes in the intervention group vs control group in the pc1 measure, adjusting for the influence of sex, age, and MMSE. This is our FSGD: GroupDescriptorFile 1 Title Between-group Class int_male Class int_female Class con_male Class con_female Variables age mmse Input 001.MR int_male 30 25 Input 002.MR int_female 40 22 Input 003.MR con_male 60 29 Input 004.MR con_female 60 21 … And this is the contrast matrix +0.5 +0.5 -0.5 -0.5 +0 +0 +0 +0 +0 +0 +0 +0 With the above contrast matrix, our interpretation would be: * Intervention > control = positive result * Intervention < control = negative result Is this the correct set up and interpretation?

Surface-based functional ROI analysis on both hemispheres at once
by Andy Kim 26 Jul '22

26 Jul '22

External Email - Use Caution Dear FreeSurfer Team, Hi. I am writing this email to ask if there is any way to do functional ROI analysis from both hemispheres at the same time, but not separately. My research question is to investigate visual hierarchy system under certain fMRI tasks using surface-based analysis. I am not interested in differences between hemispheres. There was the same question previously (https://secure-web.cisco.com/1n5iUWdnTAoX8uAScZjw9vgkzDWKHItczK2oXOxDKgvBSj…) but the answer didn't help. What I understand from the post is that I can do ROI analysis on both hemispheres just like I do it on one hemisphere. But that didn't work for me. If I can't do ROI analysis on both hemispheres at once, can I get mean beta values from ROI on each hemisphere, add them together and divide by 2 to get the average beta value? This is what I have done: # merge lh and rh labels mri_mergelabels -i lh.wang2015atlas.V1d.label -i lh.wang2015atlas.V1v.label -i lh.wang2015atlas.V2d.label -i lh.wang2015atlas.V2v.label -i rh.wang2015atlas.V1d.label -i rh.wang2015atlas.V1v.label -i rh.wang2015atlas.V2d.label -i rh.wang2015atlas.V2v.label -o lhrh.wang2015atlas.V1d+v+V2d+v.label # GL is the project name. funcroi-config -label lhrh.wang2015atlas.V1d+v+V2d+v.label -analysis GLanalysis.rh -roi rhlh.wang2015atlas.V1d+v+V2d+v.roicfg funcroi-sess -sf GLsublist -roi rhlh.wang2015atlas.V1d+v+V2d+v.roicfg funcroi-table-sess command showed an error "ERROR: there is a vertex in the label that cannot be matched to the surface. This usually occurs when the label and surface are from different subjects or hemispheres or the surface has been changed since the label was created." The command showed no error with -anlysis GLanlaysis.lh option. My original plan was to compare results between -anlysis GLanalysis.lh and -anlysis GLanalysis.rh to see if they are the same. In addition, since the atlas is surface-based, I assume I cannot use -anlysis GLanalysis.mni305. “You must specify an analysis to use. The analysis (-analysis) space must match that of the anatomical ROI space. Ie, if the anatomical ROI is defined by a surface annotation, then the analysis must be a surface-based analysis. If the anatomical ROI is defined in the volume using a segmentation or a volume label, then the analysis must be volume-based (ie, mni305 or native).” from https://secure-web.cisco.com/16alnLo11o_FBGyXyWW5_UeEPfQq5ZPaNTtjI1ZVKmT8jr… The attached files are the output from funcroi-sess with different hemispheres options. What should I do for doing ROI analysis from the both hemispheres at once? Thank you in advance. Kind Regards, Andy (Junghyun) Kim

BV/CSF index and Sulcal CSF
by Michele GRASSO 26 Jul '22

26 Jul '22

External Email - Use Caution Hello FreeSurfer Developers, My name is Michele Grasso and I am a student of the master's degree course in Computer Engineering at the University of Catania (Italy). I am interested in calculating the BV/CSF index [1] which is equal to the ratio between the sum of the volumes of gray matter and white matter and the volume of the CSF. Regarding the volume of gray and white matter, I referred to the TotalGrayVol and CerebralWhiteMatterVol volume statistics reported in the aseg.stats file. CSF volume was considered as the sum of two contributions: ventricular (Left Lateral Ventricle (SegId 4) + Left Inferior Lateral Ventricle (SegId 5) + Right lateral Ventricle (SegId 43) + Right Inf Lateral Ventricle (SegId 44) + 3rd Ventricle (SegId 14) + 4th Ventricle (SegId 15) + 5th Ventricle (SegId 72) + Right choroids plexus (SegId 63) + Left choroids plexus (SegId 31)) and sulcal CSF. I searched the list and the sulcal CSF is not segmented by Freesurfer as it is indistinguishable from bone on a T1-weighted MRI. What parameters in the aseg.stats file to consider to have a more likely measurement of the sulcal CSF? Could eTIV-BrainSegVolNotVent-ventricular volume be a good approximation? Finally, do I have to take into account the CSF statistic reported in the aforementioned file or ignore it completely? Thank you, Michele Grasso [1] https://secure-web.cisco.com/1M1Uy0HamoR49lrEsTneq1jOPjK14iKS2n5o_4kld4AC5H…

External Email - Use Caution Andrew might have a better way to do this, but you could try the following. Below you should substitute your base path to the freesurfer distribution for where /Applications/freesurfer/dev is used. 1) Setup your freesurfer environment with FREESURFER_HOME and source the setup script, e.g. zsh/bash, $ export FREESURFER_HOME=/Applications/freesurfer/dev$ source $FREESURFER_HOME/SetUpFreeSurfer.sh... output showing environment deleted ... 2) Download the tensorflow package, tensorflow-2.4.1-py3-none-any.whl, via the link, e.g. into $HOME/Downloadshttps://drive.google.com/file/d/15Qeve5FIA137KON67ehKIOyXy1N0PbAC/view?usp=sharing 3) Uninstall the existing tensorflow, $ sudo -H /Applications/freesurfer/dev/python/bin/python3 -m pip uninstall tensorflow 4) Install the downloaded tensorflow (this example assumes it is in your default Downloads folder = $HOME/Downloads). $ sudo -H /Applications/freesurfer/dev/python/bin/python3 -m pip install $HOME/Downloads/tensorflow-2.4.1-py3-none-any.whl 4) Check you have fspython in your path.  Then test the import succeeds and exit.$ which fspython/Applications/freesurfer/dev/bin/fspython$ fspython>>> import tensorflow... output deleted ...>>> ^D On Jul 25, 2022, at 11:27, Hoopes, Andrew <AHOOPES(a)mgh.harvard.edu> wrote:Unfortunately, tensorflow and M1 don’t mix well at the moment.

mri_jacobian: what are the correct files to list as arguments?
by Danielle Carrol 25 Jul '22

25 Jul '22

External Email - Use Caution Hello, I am trying to compute the Jacobian for use in VBM. I found the following command on the email archive: mri_jacobian <3d morph> <template volume> <output volume> I am assuming the 3d morph is the file mri/transforms/talairach.m3z, since this file provides the nonlinear warp. However, I am confused about which file should be the "template volume". Is this the final transformed/registered volume for each subject (i.e. ${SUBJECTS_DIR}/<subject name>/mri/brain.mgz)? Is it the fsaverage template $FREESURFER_HOME/subjects/fsaverage ? I am using version 6.0.0. Thank you, DC PhD Student University of Wisconsin-Madison

segment_subregions stats files missing?
by Alvarado, Luis 25 Jul '22

25 Jul '22

External Email - Use Caution Hi all, I ran the segment_subregions thalamus --cross on some of my subjects but I cannot find the *.stats files in the stats folder. I was wondering if I am missing something? I need the *.stats files to aggregate the results via asegstats2table to feed the mri_glmfit tool. Is there another way to do this without the *.stats files? I am using the freesurfer-linux-ubuntu20_x86_64-dev-20220716-015eeb0 build on Ubuntu 20.04.4 LTS. Best, Luis
