TRACULA cluster statistics visualization
by Makenna B McGill 09 Jan '23

09 Jan '23

External Email - Use Caution Hi Freesurfer Developers, I'm using FS v7.2 to conduct along-tract statistics using trac-all -stat, and I was wondering how to best visualize and interpret the results of the cluster-wise correction in freeview. I referenced this page ( https://secure-web.cisco.com/1Wn0Jo3ZhV2QIp8R6uvzRorN2zYdL69NgfN7PXt5cTq22h…) which describes how to do this for uncorrected statistics, and used dmri_trk2trk to embed the *perm.th13.abs.sig.cluster.mgh files produced by mri_glmfit-sim into the template .trk files (--in $FREESURFER_HOME/trctrain/hcp/syn/"$tract".display.trk). However, I'm noticing inconsistencies in the location along the tract of significant clusters between the projection of the uncorrected statistics in freeview, projection of the corrected statistics in freeview, and the cluster location as indicated by the cluster summary file (*perm.th13.abs.sig.cluster.summary.txt). I've attached the cluster summary file for FA in the rh.cst tract as an example. My understanding is that for pathways with superior-inferior orientation, points along the tract are ordered from superior to inferior. Given that this significant cluster is at a VoxX of 68 (of 80 total points along the tract), I would have thought that this cluster would be located at a more inferior position along the right cst -- instead, the cluster appears to be located superiorly. Similar to this FS user ( https://secure-web.cisco.com/1W2wWzty4LvZ-noLr4zvkjNMq5qwway38c9kYyxk8c8a4A…) I'm wondering: (1) Am I missing something regarding this embedding process? (2) Is it appropriate to embed the *perm.th13.abs.sig.cluster.mgh file to visualize the results of the cluster-wise correction? Please let me know if there is any other information you'd like me to provide. Any thoughts on where I might be going wrong would be greatly appreciated. Thank you!

Freeview label thickness: making the label outline thicker?
by Greta Tuckute 08 Jan '23

08 Jan '23

Hi developers, I am using Freeview to plot overlays on inflated surfaces with labels: freeview -f $SUBJECTS_DIR/fsaverage/surf/lh.inflated:overlay=OVERLAY_NAME.mgh:overlay_color=colorwheel,inverse,truncate:overlay_threshold=1,5:label=lh.primary.label:label_outline=1:label_color=0,0,0 This command will nicely plot the left fsaverage surface with the overlay of interest as well as the label in a black outline. My question is: the label outline is incredibly thin. I can’t seem to find a command line flag that adjusts this? In the Freeview GUI, there is a place to adjust “Edge thickness” but no matter which value I try, it does not have any effect. Is there any way to do this? Attached Freeview screenshot and label file for reference. Thanks so much for all your great work, Greta External Email - Use Caution

Re: [Freesurfer] freeview: set file as read only
by fsbuild 07 Jan '23

External Email - Use Caution You could try the usual file system commands to set permissions before opening, e.g., read only,  $ chmod 444 myvolume.mgz Or on the command line prior to running freeview, $ chmod 444 myvolume.mgz  &&  freeview myvolume.mgz You could put commands like those into a script with the file name as an argument. - R.On Jan 7, 2023, at 17:00, Aaron Tanenbaum <aaron.b.tanenbaum(a)gmail.com> wrote:        External Email - Use Caution        Hello,Is there a way to set a loaded volume as read only in freeview on the command line?_______________________________________________Freesurfer mailing listFreesurfer@nmr.mgh.harvard..eduhttps://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer

External Email - Use Caution Hi, I am using multiband = 4 and according to the dicom files, my slice timing is as below.\ My question is if it is correct to do “-stc –odd “ & “-ngroups 4” in the preproc-sess command? Thank you so much "SliceTiming": [ 0, 0.655, 0.13, 0.785, 0.26, 0.9175, 0.3925, 1.0475, 0.5225, 0, 0.655, 0.13, 0.785, 0.26, 0.9175, 0.3925, 1.0475, 0.5225, 0, 0.655, 0.13, 0.785, 0.26, 0.9175, 0.3925, 1.0475, 0.5225, 0, 0.655, 0.13, 0.785, 0.26, 0.9175, 0.3925, 1.0475, 0.5225, ],

FreeSurfer VirtualBox 7z-archive code, Ubuntu login credentials, and license file
by Jouhikainen, Pasi J 05 Jan '23

05 Jan '23

External Email - Use Caution Hello, I am an undergraduate neuroscience student at the University of Iowa. I have just started as a research assistant in a cognitive neuroscience laboratory on campus, and the principal investigator has asked me to start getting familiar with FreeSurfer. To practice, I downloaded the FreeSurfer VirtualBox VM image. This seemed like a good way to get started, especially since I have quite of bit of experience working with VMs in the past (including with VirtualBox). Based on the documentation, I would like to request the following three things: (1.) The pass code that is needed to open the 7zip archive (FS_7_2_0_ubuntu_18_04_06.ova.7z) (2.) The password for the user 'developer' that is needed to login to the Ubuntu VM. (3.) A valid 'license.txt' license file to be placed in the ~/Downloads directory inside the VM. If this is not the right email address for such a request, or if there is a different way to obtain those items other than via email, please excuse my mistake and let me know how I should proceed. Thank you in advance! Pasi Jouhikainen

mri_glmfit with doss isn't working. v7.2
by miracle ozzoude 05 Jan '23

05 Jan '23

External Email - Use Caution Hello, I have 2 groups (group 1 = 3 members, group 2 = 12 members) and I did like to regress out the effects of groups + other variables by using doss. However, whenever I specify doss with the mri_glmfit command, it gives me an error message (see below). I saw that others have experienced similar issues without any solutions. How can we solve this? Any insight is appreciated. Best, Paul mri_glmfit command: mri_glmfit --y ../../freesurfer/subjects/tracula_output/stats/mcp.avg16_syn_bbr.FA.nii.gz --fsgd dti_RPQ_3.fsgd doss --C dti_RPQ.mtx --o mcp_FA.glmdir --save-eres --nii.gz design.mtx: 0 0 0 0 0 0 0.5 Terminal output: gdfRead(): reading dti_RPQ_3.fsgd INFO: DeMeanFlag keyword not found, DeMeaning will NOT be done.
