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  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.

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.

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.

External Email - Use Caution *Description: * Our lab (https://secure-web.cisco.com/1_T3NvfJuqYnwjO4JZk_Y_pHCobABv2tYSNO634DlMF30W…) at the University of South Carolina is seeking a postdoctoral fellow to lead projects in neurodevelopmental disorders. This position focuses on investigating how genetic factors and environmental factors (e.g., early life stress) influence human brain developmental trajectory and neurodevelopmental disorders (e.g., autism) using computational models. Our lab explores the mechanisms of atypical brain development and neurodevelopmental disorders (e.g., autism) by leveraging in-house (e.g., high-resolution MRI) and public datasets (e.g., ABCD, HBCD, and etc.) 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 deep computational models and neuroimaging, supported by the brand-new Brain Imaging Center (with high-field 7T MRI) and the Biobehavioral Research Center. *Role: * As a postdoctoral fellow, you will lead this interdisciplinary project and benefit from close mentorship and collaborative opportunities in a supportive and productive research environment. You will have full access to (1) rich in-house and public datasets; (2) advanced neuroimaging platforms (3T and 7T MRI); (3) biobehavioral and clinical research resources. You will conduct a range of neuroimaging and genomics-based analyses, design and implement computational models, and lead manuscript preparation. The role also includes: (1) collaborating with international research collaborators; (2) presenting work at international conferences and institutional seminars. *What we offer:* We assist postdoctoral researchers in applying for internal and external grants and provide structured mentorship tailored to each individual's career goals. Our lab fosters a collaborative and productive environment, and we actively support postdocs in building their academic networks, generating high-quality research publications, and securing independent faculty positions. *Requirements: * The ideal candidate will be able to analyze neuroimaging (MRI) data. A strong interest in programming is essential (e.g., Python, R, Matlab, or Linux). The successful applicant will be highly motivated, possess strong analytical and problem-solving skills. Excellent communication skills and the ability to work both independently and collaboratively in an interdisciplinary research environment are also required. How to apply: submit your CV to Dr. Zhiqiang Sha (zsha(a)mailbox.sc.edu) You can also submit your application at https://secure-web.cisco.com/1cGcZDxxsp7m-L8EGTHW8C_jvjHLh1i3TSdKniExuCGuNP…

Re: Surfa update
by Hoopes, Andrew 08 Sep '25

08 Sep '25

Thanks Chris, Good point. We can get on this. I’ll investigate putting in a quick fix. The requirement for numpy<2 stems from complications with building cython utilities. I think we should ditch these utilities and instead rely on prebuilt tools (eg scipy). It sacrifices some minor runtime, but will relieve major distribution headache. That project is a bit more involved but hopefully we can get to it soon. Andrew From: Rorden, Chris <RORDEN(a)mailbox.sc.edu> Date: Thursday, August 14, 2025 at 12:22 PM To: freesurfer(a)nmr.mgh.harvard.edu <freesurfer(a)nmr.mgh.harvard.edu>, Hoopes, Andrew <AHOOPES(a)mgh.harvard.edu> Subject: Surfa update External Email - Use Caution Hello Would it be possible to release a version of surfa that uses numpy 2? For examples, the original version of synthsr and the one included with FreeSurfer rely on Python versions that are end of life. I upgraded this to use up to Python 3.13 (latest version supported by TensorFlow), but the Surfa support demand for numpy 1 requires special environment so it does not play well with other tools (surfa pyproject.toml notes 'numpy<2.0’). I really do not want to maintain a separate fork, and if we could upgrade surfa the maintained FreeSurfer project could include versions of these scripts that support maintained versions of Python. For the time being, here is my fork: https://secure-web.cisco.com/1Tj_72h5VBPhEzQKtS8Wnrte2Od2rEUMf2iVThbaWZrFxe… Thanks for all your work, -chris
