Brainstem segmentation without pre-processing
by Ganjizadeh, Ali, M.D. 28 Dec '23

28 Dec '23

External Email - Use Caution Good evening, I am trying to work with segmentBS.sh. I want to pass my .nii.gz files that are already pre-processed with HD-BET, but I don't want to use recon-all as the first step because it takes a lot of time. I also tried recon-all -autorecon2 and 3, but it resulted in an error. Is there any specific command that I will be able to pass my files directly to segmentBS.sh? Or is there any command for recon-all to only make subjects without processing or fast processing?

External Email - Use Caution  On linux, that file is under $FREESURFER_HOME/bin and will be found in your PATH after you setup the Freesurfer environment, e.g. for the 7.2.0 release installed via the .rpm file, you setup the environment with, $ export FREESURFER_HOME=/usr/local/freesurfer/7.2.0-1 $ source $FREESURFER_HOME/SetUpFreeSurfer.sh -------- freesurfer-linux-centos7_x86_64-7.2.0-20210720-aa8f76b -------- Setting up environment for FreeSurfer/FS-FAST (and FSL) FREESURFER_HOME   /usr/local/freesurfer/7.2.0-1 FSFAST_HOME       /usr/local/freesurfer/7.2.0-1/fsfast FSF_OUTPUT_FORMAT nii.gz SUBJECTS_DIR      /usr/local/freesurfer/7.2.0-1/subjects MNI_DIR           /usr/local/freesurfer/7.2.0-1/mni $ which segmentBS.sh /usr/local/freesurfer/7.2.0-1/bin/segmentBS.sh $ segmentBS.sh -h      ERROR: cannot find Matlab 2014b runtime in location:      /usr/local/freesurfer/7.2.0-1/MCRv84… rest of output deleted .. So if you have not already installed the MATLAB runtime environment for the segmentBS.sh script, then you need to run the Matlab install script we provide.  For the Freesurfer install under /usr/local on linux, the Matlab install needs to be done with root/admin privileges which you can try via the sudo option, $ cd $FREESURFER_HOME/bin$ sudo  FREESURFER_HOME=$FREESURFER_HOME  ./fs_install_mcr  R2014b … you will see output from downloading and installing the matlab runtime under /usr/local/freesurfer/7.2.0-1/MCRv84 …You should follow the instructions from the script output about how to set LD_LIBRARY_PATH, e.g., On the target computer, append the following to your LD_LIBRARY_PATH environment variable: /tmp/tmp.e23XcWLTeV/install-target/v84/runtime/glnxa64:/tmp/tmp.e23XcWLTeV/install-target/v84/bin/glnxa64:/tmp/tmp.e23XcWLTeV/install-target/v84/sys/os/glnxa64: Your paths may be different, but you would modify the LD_LIBRARY_PATH setting as follows; I just cut and pasted the /tmp/* paths anover after "export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:”, $ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/tmp/tmp.e23XcWLTeV/install-target/v84/runtime/glnxa64:/tmp/tmp.e23XcWLTeV/install-target/v84/bin/glnxa64:/tmp/tmp.e23XcWLTeV/install-target/v84/sys/os/glnxa64 You could follow the same instructions as listed above for the 7.4.0 release, i.e.. change 7.2.0 to 7.4.0 in all the commands (and corresponding output should list 7.4.0 instead).  The segmentBS.sh in 7.4.0 might ask for a newer Matlab version like MCRv97.   In that case, the sudo command to run the fs_install_mcr script would be,$ sudo  FREESURFER_HOME=$FREESURFER_HOME  ./fs_install_mcr  R2019b Once Matlab runtime is installed, try running segmentBS.sh again, $ segmentBS.sh -h  Directory of subject to process:    /usr/local/freesurfer/7.2.0-1/subjects/-h does not exist So change SUBJECTS_DIR to the path containing the subject data you want to process, $ export SUBJECTS_DIR=/path/to/my/subjects … then try running again ... - R.

External Email - Use Caution Greetings, I have tried FreeSurfer 7.4.1 and 7.2.0 for CentOS7. But neither of them has segmentBS.sh in the files. Could you help me to find the file? I want to pass T1 MRIs (in which the skull is removed already) and get brain stem segmentation only. Could you explain what the fastest command is to do this job?

question regarding echo spacing and epi factor in TRACULA
by Hu, Bojia 22 Dec '23

22 Dec '23

Hello there, When we were trying the TRACULA tutorial, we noticed a discrepancy between the downloaded script and the wiki page. The echo spacing is set as 0.000689998 in the script, but it is exemplified in ms on the wiki page. For the epifactor, it is set as 139000.96811584961115829321 in the script, but on the wiki page it is 140. We are wondering which units we should be using for our dataset. Our protocol says that echo spacing is 0.55ms, and EPI factor is 116. Thank you for your help. Warm regards, Cynthia Hu

SUBJECTS_DIR writing permissions to run hippocampal/amygdala subfields
by Heese, E. van (Eva) 22 Dec '23

22 Dec '23

External Email - Use Caution Dear FreeSurfer support team, I am running into some issues regarding the mandatory SUBJECTS_DIR writing permissions when running the hippocampal and amygdala subfields segmentation functionality<https://secure-web.cisco.com/1GxtLaQMhc8dCLk40Dqxx5gjSJCGqioQxX7dJnX4YO4XoD…> (segmentHA_T1.sh). I am using FreeSurfer 7.3.2 on a slurm server. We have a shared FreeSurfer installation which is the FREESURFER_HOME location for many users, hence the absence of writing permissions. When running the subfield segmentations, I get this error: mv: replace 'imageDump.mgz', overriding mode 0444 (r--r--r--)? Even when overriding this (by typing y), the error results into issues with the segmentations because it cannot access the imageDump.mgz file and thus cannot use it as the starting template for the segmentation. This has been suggested and confirmed by Philipp Saemann and Juan Eugenio Iglesias in separate correspondence. The short-term solution offered by our server admin was to make a local copy of the FreeSurfer installation (to be able to get writing permissions) and set the FREESURFER_HOME variable to this local copy. This seems a bit devious, considering many FreeSurfer users might face a similar issue on shared clusters without writing permissions. Is there another workaround possible? Thanks for your help. Best wishes, Eva van Heese ______________________________________________________ AmsterdamUMC disclaimer : http://secure-web.cisco.com/181PMcOVEvWHrKhQAbaRQ6z6TR591a4a86em9ZjTSVgyLTj…

Re: [Freesurfer] Freesurfer/Freeview Version Compatibility
by fsbuild 20 Dec '23

20 Dec '23

External Email - Use Caution The freesurfer 6.X and 7.x release release notes summarize some changes for Freeview (listed below) since version 5 was released in 2013.   If none of the improvements in features/stability are relevant to what you are doing, then I don’t see why you could not revert to the older 5.X software.  But if you run into issues with a now ~10 year old version of Freeview, we may tell you to use the latest 7.4.1 release from June of 2023. - R. - - - - -  • New: interface for x virtual frame buffer (fsxvfb). When you run freeview from fsxvfb, no X server is needed. This is good for taking a bunch of pictures when you don't want freeview popping up all the time. Eg, fsxvfb freeview orig.mgz -ss mypic.png —quit • The filled.mgz can now be edited instead of the wm.mgz. The advantage to this is that filled.mgz is slightly further in the process and it is more intuitive. The filled.mgz is actually a segmentation of the subcortical mass. In Freeview, you can view it in outline mode, meaning that the edges of the segmentations are actually the surface that you are editing. After that, run recon-all with the -autorecon2-wm -autorecon3 options, just as you would if you had edited the wm.mgz..Landmark-based repositioning of surfaces. Did you ever want to just make the surface move through a certain point? You can do that now by creating point sets in freeview. Create a separate point set for each surface (lh, rh, white, and pial), then save it in subject/surf with a file name repos.$hemi.$surf.json where $hemi is either lh or rh and $surf is either white or pial. Then run recon-all with the -autorecon2-surfonly -autorecon3 options. Note that you can do this interactively inside of FreeView as well; look under Tools->Resposition Surface. If you do it interactively, the surface may be overwritten next time recon-all is re-run, but it gives you a chance to play with the repositioning.freeview - can now load and visualize diffusion orientation distribution function (ODF) data.FreeView changes: surfce path and label editing, surface annotation editing, automatic segmentation assisted by Geodesic Matting algorithm, displaying two time courses at the same time, better support for Mac (petsc error fixed on Mac) On Dec 20, 2023, at 14:07, Edwards, Vincent <Vincent.Edwards(a)utdallas.edu> wrote:        External Email - Use Caution        Hi, I'm following up on my quick question from this time last week. I have several brains that I sent through recon-all using Freesurfer 7. If I wanted to use Freeview on Freesurfer version 5 to do pial/wm/and control point edits, would I be able to do recon-all through Freesurfer 7?  Years ago, someone asked if they could do recon-all in an older version of Freesurfer and edit in a newer GUI. Doug said that was fine. My question is basically the inverse of their problem. I assumed that since Freeview is a GUI, the version used shouldn't have any actual impact on things as long as we returned to version 7 to recon-all. I just want to confirm that my assumption is correct?The pipeline would be: F7 (recon-all), F5 (edit with freeview), F7 (recon-all for pial/wm/cp's)Thanks,Vincent Edwards_______________________________________________Freesurfer mailing listFreesurfer@nmr.mgh.harvard.eduhttps://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer

Evaluating the Reliability of Optic Chiasma Analysis in Freesurfer
by Knut J Bjuland 20 Dec '23

20 Dec '23

External Email - Use Caution Dear FreeSurfer experte I am currently engaged in a detailed volume analysis project where I am utilizing the optic chiasma as a key focal point. In this context, I'm specifically interested in understanding how reliable the optic chiasma measurements are when analyzed using Freesurfer software. This includes assessing the accuracy of volumetric data, the precision of segmentation processes, and the overall consistency of results obtained across different datasets. Given the critical role of the optic chiasma in neuroanatomical studies, it's imperative to ensure that the tools we use provide dependable and repeatable outcomes. Therefore, any insights into the efficacy of Freesurfer in handling optic chiasma data would be greatly appreciated, as it will significantly impact the interpretation and validity of our research findings.
