Re: [Freesurfer] Recon-all-clinical error: Illegal instruction Error in SynthSeg

External Email - Use Caution   Thanks for reporting this.  This posting indicates there is a difference in defining that for arm64 compared to intel architectures,  https://secure-web.cisco.com/1FTmSa1QjGMsQB8Xf5Zs… We will look into it along with producing an updated arm64 build.  You could try making the change described in the posting in the SynthSeg code if you like. You will not encounter that error in any existing/previous release, 7.4.1 ... 7.3.2 as you are using a new arm64 development build which is post the 7.4.1 release. - R.

[WARNING: ATTACHMENT UNSCANNED]Errors in recon-all for post-operative T1 images
by Jingping Xie (SBS) 27 Sep '23

27 Sep '23

External Email - Use Caution Hello FreeSurfer Developers, I'm attempting to compare the pre-operative (pre-op) and post-operative (post-op) anatomical images for a group of patients who underwent brain tumor resection. During the operation, part of the brain tissue and the skull were removed, and I would like to mark or label the removed/changed region (both cortical and subcortical) in the pre-op intact reconstructed brain. For one sample subject (tumor on the left side), I have completed the recon-all for the pre-op T1 images without any error reported. However, for the post-op images, the key volumes such as T1/brainmask/wm.mgz were generated from recon-all steps but failed in getting almost all surfaces. The related recon-all log and T1.mgz can be found in the attachment. I wonder whether (and how to) a detailed quality check or troubleshooting could solve such recon-all errors? Could I reconstruct the post-op brain when part of the structure is missing and reach my original goal? I used FreeSurfer 7.4.1 on MacOS Ventra 13.0. Thank you for your kind assistance.

Re: [Freesurfer] Running MATLAB on a MAC PRO

External Email - Use Caution  You can try using the fs_install_mcr script to install the matlab runtime environment instead of using a generic or full install of Matlab on the machine.  Below the PATH to FREESRUFER_HOME is listed as /Applications/freesurfer/7.4.1, but you should change it to be whatever you installed on your machine.   The 7.4.1 release was tested with R2019b $ export FREESURFER_HOME=/Applications/freesurfer/7.4.1 $ source $FREESURFER_HOME/SetUpFreeSurfer.sh <... output showing SUBJECTS_DIR and other environment variables> $ cd  $FREESURFER_HOME/bin $ sudo FREESURFER_HOME=$FREESURFER_HOME  ./fs_install_mcr  R2019b I think that sets things up so the libmwm* libraries are in the freesurfer tree under the path, $FREESURFER_HOME/MCRv97/bin/glnxa64.- but you should check that path. Then you can try adding the path you verified, e.g., $FREESURFER_HOME/MCRv97/bin/glnxa64,  to the head of LD_LIBRARY_PATH and remove any other entries to a different MATLAB distribution. - R..

Potential bias in the base template
by Maksim Slivka 26 Sep '23

26 Sep '23

External Email - Use Caution Hi FreeSurfer Community, I plan to use longitudinal FreeSurfer to process a set of longitudinal scans that are likely to create a bias in the base template. Specifically, our study consists of 3 scans acquired within the first 20 weeks and a subsequent scan acquired 2 years after the third scan. >From the original publication on longitudinal FreeSurfer, I understand that the longitudinal scans are treated equally and do not require to be evenly distributed in time, and that the cross and base images are only used to initialize the longitudinal processing. However, my concern is that the resulting template, based on the median, will be too similar to the first three scans. Would this negatively impact the results of the 4th scan, due to the inherent bias of the template? Has any group investigated this before? Any feedback would be appreciated! Best regards, Maksim

External Email - Use Caution  I don’t see an error message in  what you posted below. I would not assume changing soft links to actual copies of the same file (by a different name) will work, i.e., anything that makes a soft link may subsequently test for a soft link using the link name.  That test will fail if the soft link has been replaced by an actual (duplicate) copy of the file.  The expectation is when writing output e.g., during recon-all, that SUBJECTS_DIR points to a linux compatible file system that supports creating all the Linux file system file types (including soft links) and support all Linux file privileges. -R.

I'm currently working on Ubuntu 22 and processing the images from an exFAT drive.After digging a bit, I realised that symbolic links cannot be created on exFAT drives. I then came across another post that suggest to change all 'ln' to cp instead. While that works for the remaining steps. It started exiting with errors at this stage.The stage where it stops#@# Qdec Cache preproc lh white.K fsaverage Wed Sep 13 15:40:33 +08 2023The error that was in the error log.CMD mris_preproc --s ED751_SAG_MPRAGE_p2_NON-SSc.nii --hemi lh --meas white.K --target fsaverage --out lh.white.K.fsaverage.mghWhat should I do to resolve this issue? Cheers,Mervin Important: This email is confidential and may be privileged.
