External Email - Use Caution If you edit the file $FREESURFER_HOME/FreeSurferEnv.csh such that line 183 does not contain the semicolon between the “if” and “then” in your MacOS freesurfer installation, that should eliminate the error you listed before the job was killed.   So you could try running your recon-all again on MacOS (and do not run anything else on the machine during recon-all, e.g., browsers, videos or anything that would consume additional memory). - R.

External Email - Use Caution  The freesurfer distribution is not currently tested on or supported for Ubuntu 24.  There is however a .deb installer file for Ubuntu 22.https://secure-web.cisco.com/1oNullxLzc9liUdhfga5GqW1fLnd8376FUzplKtAZeU… are instructions about how to create a generic Ubuntu 22 VM, after which you can run the above installerhttps://drive.google.com/file/d/1uNwv29fCeuMHrmTyXw94ZSuroNsPOxu-/… - R.

External Email - Use Caution  Apart from the output about the if statement, it looks like your recon-all command did run and then was killed because mri_synthstrip used too many system resources.   That is unless the command took no time to run and immediately exited.     If the command exited immediately after you entered it on the terminal, then the output about the if statement could indicate there is something not right with your recon-all arguments. Check you can run mri_synthstrip command directly.  A command with actual arguments and processing to do would be a better test, but at least try, $ mri_synthstrip -h You could try reverting recon-all to the old behavior where it will not run the newer mri_* commands as part pf the recon-all pipeline by setting the environment variable FS_V8_XOPTS=0.    That should reduce the chances the system will kill the process because of heavy resource usage. $ export FS_V8_XOPTS=0 && recon-all -s NVR-1 -sd /Volumes/INTENSO/Projects/NeuroVR+/MRI/recon/NVR-1_recon -i /Volumes/INTENSO/Projects/NeuroVR+/MRI/Nifti/NVR-1_nii/5_t1_tfl3d_sag_ti1090_fa9_tr2700_09mm_p2.nii.gz -T2 /Volumes/INTENSO/Projects/NeuroVR+/MRI/Nifti/NVR-1_nii/6_t2_space_sag_081x081x09mm_p2.nii.gz -T2pial -all - R.

Re: RedHat installation

External Email - Use Caution  You can try the .rpm installer that matches the RedHat system.  So you could try the CentOS7 rpm on a RedHat7 system, and the Rocky8 rpm on a RedHat8 system.  I’m not sure if the rocky8 installer will work on RedHat 9. - R.On Sep 8, 2025, at 08:48, Gomez-Acebo Ruiz, F.

Misaligned datasets with identical headers in Freeview
by Chourrout, Matthieu 12 Sep '25

12 Sep '25

External Email - Use Caution Hi the FreeSurfer team! I have generated two datasets with identical headers, but there is an offset between them when rendering them in Freeview bundled with FreeSurfer 8.0.0 and FreeSurfer 8.1.0 (Ubuntu 22 DEB releases in WSL2 on Windows 11 and on Ubuntu 22). I did the same test on two workstations, and I had no issue when switching back to FreeSurfer 7.4.1 (Ubuntu 22 DEB releases in WSL2 on Windows 11). It's unclear to me if it's only a rendering issue or if the CLI commands such as mri_segstats would also be impacted. I can send a private link to the test data.

PhD positions in neurodevelopmental disorders
by Z S 10 Sep '25

10 Sep '25

External Email - Use Caution Description: Our lab (https://secure-web.cisco.com/1bJ41rR8jEuup-ZfnltW6Mk-VrUnLDy1GAZgmiB_R4Nt4P…) at the University of South Carolina is seeking *PhD students in Neuroscience*. Our lab is affiliated with the Carolina Autism & Neurodevelopment Center, the Institute for Mind & Brain, and working closely with the McCausland Center for Brain Imaging in Columbia, center of SC Metropolitan Statistical Area. Our lab explores the mechanisms of atypical brain development and neurodevelopmental disorders (e.g., autism spectrum disorders) by leveraging statistical modeling to bridge genetic variation, neural circuitry, exposure (e.g., early life adversity) and psychopathological phenotypes, and treatment outcomes. These innovative projects will leverage state-of-the-art machine learning models and neuroimaging, supported by the brand-new Brain Imaging Center (with 3T and high-field 7T MRI scanners) and the Biobehavioral Research Center at the University of South Carolina. This position provides an excellent opportunity for a motivated student to gain hands-on experience with neuroimaging (e.g., MRI) and biomedical research techniques. The candidate will have full access to rich in-house and public datasets, and advanced neuroimaging platforms. Our lab fosters a collaborative and productive environment, and we actively support PhD students in generating high-quality research publications, applying for fellowships and securing their future career paths. Key roles: · Data collection, analysis; present results and publish papers under the PI’s supervision · Collaborate with lab members and international collaborators · Keep up-to-date on relevant studies and methods, and actively discuss them with the PI · Present your work at national and international conferences Requirements: · Bachelor’s or Master’s degree in a relevant field (e.g., neuroscience, psychology, and related area) · Experience with clinical and MRI data analysis is preferred. · Candidates with coding experience are preferred. How to apply: Please submit your CV to Dr. Zhiqiang Sha (zsha(a)mailbox.sc.edu ).
