Freeview on debian
by Gian Marco Duma 20 May '20

20 May '20

External Email - Use Caution Hi everyone, I have a problem with freeview. My university created for me a virtual machine in a small analysis cluster. Unfortunately, they installed Debian 4.19.98. I read that freeview has some problems with Debian, and in fact I am not able to open it. Unfortunately I need to visualize the data because we are conducting an anatomical study with patients with lesions. All the processes I ran until now, like automatic segmentation and surface generation like recon all, worked perfectly, but I need to visualize the data. Do you have suggestions to solve this problem? Thanks

Freesurfer version 7.0.0 and hippocampal segmentation
by Vanessa Cropley 20 May '20

20 May '20

External Email - Use Caution Hello Freesurfer team, I have just become aware of the release notes concerning v7.0.0 being recalled and not to be used, with the recommendation to use v7.1.0 instead: https://surfer.nmr.mgh.harvard.edu/fswiki/ReleaseNotes I have a couple of questions about the implications of this recall. We have processed a large dataset using freesurfer version 6, with all subjects being processed (recon-all) with the same version/platform. We would now like to segment the hippocampal subfields using the enhanced version of the module as outlined here: https://surfer.nmr.mgh.harvard.edu/fswiki/HippocampalSubfields which requires Freesurfer 7. We have successfully run the hippocampal segmentation using freesurfer_v7.0.0_dev_20200405 (7.1 was not available at the time). My questions: 1. Given the recall of v7.0.0, does this mean that we should re-do the hippocampal segmentation that used v7.0.0 with v7.1.0? In other words, are all functions within v7.0.0 to be avoided, or just the recon-all stream? 2. Given that the recon-all was processed with v6, is it ok to perform the hippocampal subfield segmentation with v7? I understand that it is fine to perform post-processing functions outside the recon-all stream with newer versions (provided recon-all was done with the same version). Is my understanding correct? Thank you for your assistance. - Vanessa

External Email - Use Caution After running the permutation and finding significant clusters, I am trying to calculate the value for each participant for these significant clusters. The perm.th30.abs.y.ocn.dat contain the raw values, and I am trying to get the adjusted values accounting for age, sex, and ICV (this is a three group design). The X matrix was 240x12 (see attached file) * Column 1: 1s for Group 1 and 0s for Group 2 and 0s for Group 3 * Column 2: 0s for Group 1 and 1s for Group 2 and 0s for Group 3 * Column 3: 0s for Group 1 and 0s for Group 2 and 1s for Group 3 * Column 4: Age for Group 1 and 0s for Group 2 and 0s for Group 3 * Column 5: 0s for Group 1 and Age for Group 2 and 0s for Group 3 * Column 6: 0s for Group 1 and 0s for Group 2 and Age for Group 3 * Column 7: Sex for Group 1 and 0s for Group 2 and 0s for Group 3 * Column 8: 0s for Group 1 and Sex for Group 2 and 0s for Group 3 * Column 9: 0s for Group 1 and 0s for Group 2 and Sex for Group 3 * Column 10: zICV for Group 1 and 0s for Group 2 and 0s for Group 3 * Column 11: 0s for Group 1 and zICV for Group 2 and 0s for Group 3 * Column 12: 0s for Group 1 and 0s for Group 2 and zICV for Group 3 I was not sure how to modify the last line in your code in order to calculate adjusted values accounting for age, sex, and ICV for each participant. Your code: There is not an easy way to do it, but you can do it in matlab cd glmdir X = load('Xg.dat'); y = load('perm.th30.abs.y.ocn.dat'); beta = inv(X'*X)*X'*y; yhat = X(:,[i j k ...]*beta([i j k ...]) where i j k ... indicate the factors you want keep in your data. Each factor gets a column in the design matrix (and a beta).

Re: [Freesurfer] Freeview on debian

External Email - Use Caution Hello Gian, Maybe you can report back with the version of Debian linux you are using so we could look into it. You could try downloading and running the Ubuntu VM image we have with freesurfer 6 and 7 beta release installed on it.  If you are going to run the VM on a linux machine, then you should still be able to follow the instructions listed for setting up the VM on either the Mac or Windows after you install VirtualBox on your linux machine.  The links to the VirtualBox setup instructions for MacOS and Windows are here,https://surfer.nmr.mgh.harvard..edu/fswiki/VM_67 The link to the Ubuntu VM image is on this page where it lists FStutorial_clone_2.7z followed by the link when you click on “image”.  You will need a 7zip program to uncompress it (as explained in Mac and Windows instructions). Once you get the Ubuntu VM running and login as userid developer, you can update the beta 7 release to the latest 7.1.0 release with the instructions below. You can email me directly if you run into something. - R. - - - - -  Updating Ubuntu FS 7 beta release to the current 7.1.0 release - - - - Log into the Ubuntu VM as aid developer. Download the latest release - currently 7.1.0 - from https://surfer.nmr.mgh.harvard.edu/pub/dist/freesurfer/7.1.0/freesurfer-lin… Let's assume after the download the archive file is located in your downloads folder under the path, ~/Downloads/freesurfer-linux-centos7_x86_64-7.1.0.tar.gz Locate your previous version 7 release under the path /usr/local/freesurfer $ ls /usr/local/freesurfer 6.0.0-1  7.0.0-1 Remove the previous version 7 release, here 7.0.0-1, $ cd /usr/local/freesurfer $ sudo rm -rf  7.0.0-1 Expand the archive for the new release from your downloads folder, $ sudo  tar  zxpf  ~/Downloads/freesurfer-linux-centos7_x86_64-7.1.0.tar.gz Now move the newly created ./freesurfer subdirectory from the archive to be the name of the new release, $ sudo mv freesurfer 7.1.0-1 Check to see files are there, $ ls 7.1.0-1 <output deleted> Finally, replace your existing $HOME/.bashrc file with the attached bashrc file which will allow you to run either the 6.0.0 or 7.1.0 release.  NOTE - if you have made changes to your $HOME/..bashrc file since you started using the VM, then you may want to merge your current $HOME/.bashrc with the contents of the attached bashrc in order not to lose your changes. You could also diff the 2 files and add manually edit in the changes from the attached bashrc. With the new bashrc in your downloads folder as ~/Downloads/bashrc, then to diff the files, $ diff  ~/Downloads/bashrc  $HOME/.bashrc To simply replace the old bashrc in its entirety, $ cp -p -f  ~/Downloads/bashrc  $HOME/.bashrc Once your new $HOME/.bashrc file is in place (which should use use the 7.1.0-1 release by default), then start a new terminal window.  You should see the following output: -------- freesurfer-linux-centos7_x86_64-7.1.0-20200511-813297b -------- Setting up environment for FreeSurfer/FS-FAST (and FSL) FREESURFER_HOME   /usr/local/freesurfer/7.1.0-1 FSFAST_HOME       /usr/local/freesurfer/7.1.0-1/fsfast FSF_OUTPUT_FORMAT nii.gz SUBJECTS_DIR      /usr/local/freesurfer/7.1.0-1/subjects TUTORIAL_DATA     /home/developer/tutorial_data MNI_DIR           /usr/local/freesurfer/7.1.0-1/mni WARNING: /usr/local/freesurfer/7.1.0-1/fsl_507/bin does not exist.

Re: [Freesurfer] Longitudinal edits on norm.mgz instead of brainmask
by Elena Pozzi 19 May '20

External Email - Use Caution Hi Douglas, Thank you very much for your answer. I tried the command you suggested and it did not seem to transfer the edits, so I added the flag -keep_mask_deletion_edits and that seems to work. Would you mind confirming that the final command mri_mask -keep_mask_deletion_edits brainmask.mgz norm.mgz brainmask.mgz is safe to run to transfer the edits (i.e., voxel deleted) from the norm.mgz to the brainmask.mgz? Thanks again! Elena

Freesurfer hippocampal segmentation in patient with temporal lesion
by Linda Zhang 19 May '20

19 May '20

External Email - Use Caution Dear all, I have a subject for whom I need to segment the right hippocampal and amygdalar subfields. However, they have a significant white matter lesion and large ventricles in the right temporal lobe, such that skull-stripping consistently cuts away the cortex in that region, and subsequent aseg and surface reconstruction is inaccurate. My question is, does the hippocampal subfield module (I'm using the old segmentHA_T1.sh for consistency with our other subjects) use the aseg froom recon-all as a basis for its segmentation? If I just manually correct the hippocampus in the aseg and try running the subfields again, would it work? I've tried adjusting the skull-strip and no combination of wsthresh and no-wgcsaatlas has helped. I'm running FS6.0 on Ubuntu 18. Thank you! Regards, Linda
