Fw: SuperSynth equivalent of quantifyHAsubregions.sh

It took 12 minutes per subject (though we still needed to run Freesurfer 8 for the cortical parcels — this took longer). The PI will use the extra-cerebral regions for her study, though it will be a while before we have a paper to cite you. I wondered, though, whether there was a counterpart to quantifyHAsubregions.sh for SuperSynth (i.e., extract stats into NumSubjects x NumParcels spreadsheet)?

Making Matlab visible to Freesurfer?
by alex han 04 Feb '26

04 Feb '26

External Email - Use Caution Hello, I am running freesurfer 7.4.1 on Ubuntu 22, and am trying to run local GI on subjects but am having trouble making Matlab visible to freesurfer. I have tried using the runtime script in the wiki and currently have Matlab 2014b downloaded after getting an academic license. I tried using the cd <FreeSurferRootDirectory> && ln -s <MatlabRootDirectory> MCRv84 as well. In both cases running the recon-all -s <subj> -localGI command outputs the error in the log attached. I'm new to freesurfer and matlab, so I'm not sure how to start. I scrolled through the email archives, but couldn't find anyone with as simple a problem as mine on the same versions I'm using. Any help would be appreciated. Thank you very much

FR[AI]ME - a MacOS QuickLook plugin built with FreeSurfer in mind
by Ross Callaghan 04 Feb '26

04 Feb '26

External Email - Use Caution Dear FreeSurfer mailing list, We are pleased to announce the availability of FR[AI]ME by AINOSTICS™, a new macOS QuickLook extension for previewing common neuroimaging file formats that we hope will be beneficial to the FreeSurfer community. What is FR[AI]ME? FR[AI]ME is a lightweight macOS QuickLook extension that provides instant previews of common neuroimaging file formats directly in Finder. By pressing the spacebar, users can quickly visualize DICOM (.dcm, .IMA), NIfTI (.nii, .nii.gz), and FreeSurfer (.mgh, .mgz) files without launching a full imaging application. Why did we develop it? Recent changes in macOS 15.0 deprecated the long-standing DTI-TK QuickLook plugin that many in the neuroimaging community relied on. FR[AI]ME was developed as a modern replacement for the DTI-TK plugin, incorporating new features not previously possible. What's new in FR[AI]ME? FR[AI]ME includes a number of improvements over the original DTI-TK plugin, including support for new file formats such as DICOM and a choice of colourmaps per image. An exciting new feature in v2.0.0 enables folder previews, allowing you to view images overlaid over one another - for instance, to view segmentations directly over their base images. How can FR[AI]ME help FreeSurfer workflows? FR[AI]ME v2.0.0 is built with FreeSurfer workflows in mind, automatically displaying FreeSurfer segmentations using the standard lookup table. The folder preview feature further enables you to view FreeSurfer segmentation files directly overlaid on the base anatomical image. Why we ask for your support FR[AI]ME includes a free mode with limited metadata previews. A small annual subscription, comparable to the cost of coffee in a working week, unlocks full image previews. This helps cover ongoing development costs for AINOSTICS™, a small UK-based startup, as well as Apple's mandatory developer and distribution fees. Your support enables us to maintain and improve the plugin, delivering new features like those in v2.0.0. We hope FR[AI]ME is a useful replacement for those who relied on the DTI-TK QuickLook plugin and can be a helpful tool for all FreeSurfer users. FR[AI]ME is available as a simple install on the Mac App Store at the link below. https://secure-web.cisco.com/1GU-ttFUL-B535GgpEoSSSP7-QZ7w4XHxrpuNq2IUQiwt0…

recon-any on the dev version: MODEL NOT FOUND
by Hajer Karoui 03 Feb '26

03 Feb '26

External Email - Use Caution Hello, I am trying to build my recon-any docker container, however, there aren't any recon-any models under /usr/local/freesurfer/models . I used the dev version as instructed on the recon-any page<https://secure-web.cisco.com/1IWMAnbFsrK7hUPXbUYFFyownliON0lfj8kai-AYb1tFVM…> : https://secure-web.cisco.com/1wqyV9QaH0DR_i5QozZC-H1CIPo692K7W9DuzDSMFhjOld… The line in the recon-any script (on the github repo<https://secure-web.cisco.com/1Y6OZwVR9AsipMHQdhwC2Wt__u5i2tFQbtRNBzaKMK2KTM…>) to download the model contains a work that doesn't actually work. I get Exit code 8 from wget (server error / HTTP error). So the URL is likely wrong or the file doesn't exist at that location. https://secure-web.cisco.com/1qWCICkPxU-ruG3rUhQv-XwI8SbaLM4OiAg-DKIR3Xbp1P… Looking forward to your advice and thanks.

Issue accessing WMH-Synthseg required files
by Cui, Qiming 02 Feb '26

02 Feb '26

External Email - Use Caution Dear Freesurfer team, I am trying to use mri_WMHSynthseg for white matter hyperintensity segmentation. I have installed the latest dev version, and I understand I need to download an atlas file from " https://secure-web.cisco.com/1rKqiV3c2UqdiIsJcAkgN6Rp80ECVnAQhuP-ybfrZvES9u…". However, I get a 404 error when I try to access this url. Upon examining the server, I see that https://secure-web.cisco.com/1mPu-NE2sUuQ7fyqENpvjVu3_TN_mht4HgGfcxc1kLZmIQ… is empty. Could you help me gain access to this atlas file? Thank you. Best, Gavin Cui

Electrode coordinate transformation to MNI152 space
by Kerezoudis, Panos, M.D., M.S. 01 Feb '26

01 Feb '26

External Email - Use Caution Hi, I have run the cvs registration to MNI152 space on my subject’s T1 nifti volume (‘cvs_avg35_inMNI152’). Process was uneventful and the necessary files were generated. How do I convert now the intracranial electrode coordinates from native to MN152 space? I have stored the coordinates in a .txt file, essentially as a matrix, channels by xyz physical coordinates (AC=center of origin). I have not been able to find anything helpful online. Thank you very much in advance, Panos Kerezoudis

Regarding Collaboration and Partnerships
by Ozgur Akbulut 31 Jan '26

31 Jan '26

External Email - Use Caution Dear Sir or Madam, We are a company established in Turkey under the names beyinverimerkezi.com and braindatacenter.com, dedicated to providing measurement and reporting of brain volumetric values to MR Imaging Centers, private hospitals, and the Turkish Ministry of Health. Our primary objective is to deliver the data we obtain to neurologists, psychiatrists, and neurosurgeons prior to diagnosis, thereby guiding early detection and treatment strategies, as well as evaluating the efficacy of implemented treatments through controlled measurements. In pursuit of this goal, we would like to request an online meeting to explore opportunities for collaboration, integration to your ecosystem, and assuming roles that will contribute to the development processes. The meeting will include participation from our Turkish team: Prof. Dr. Niyazi Acer, who received his training at Johns Hopkins University; our software partner, Özgür Akbulut; and Turgay Şahin, the brain researcher and originator of the core concept. We eagerly anticipate discussing a suitable date and time, taking into account the time difference between our locations. We extend our profound gratitude to every FreeSurfer volunteer for their invaluable contributions to the field. Özgür Akbulut CTO - Brain Data Center ozgurakbulut(a)braindatacenter.com http://secure-web.cisco.com/1Nv6cgLfVYARoj7aVwFaISaxYAGpnS9POwcvMOuJue_MIHT… +90 533 541 19 00
