HBT/FS60/CA segmentation
by Yasmine Salman 20 Oct '23

20 Oct '23

External Email - Use Caution Dear Freesurfer Developpers, When I look at the FreeSurfer documentation on hippocampal segmentation, I see that it is possible to obtain different segmentations in addition to the 'traditionnal ' freesurfer 7 one: - HBT: the hippocampus is subdivided into head, body and tail. - FS60: it mimics the FreeSurfer 6.0 hippocampal module, i.e. there is no head/body subdivision for the hippocampus. no head/body subdivision for hippocampal sub-regions. - CA: the "internal" labels (GC-ML-DG and molecular layer) are absorbed by the CA subfields. When I run the command line: segmentHA_T1.sh bert I get files: hipposubfields.lh.T1.v21.stats which contain the volumes of the freesurfer 7 segmentation but not the other segmentations. I would like to generate a .stat file (one/subject) of segmentation type 'CA' , how can I do this? Thank you, Best, Yasmine

Problem with mri_glmfit
by Monami Nishio 19 Oct '23

19 Oct '23

External Email - Use Caution Dear whom may concern Hello Freesurfer Developers, I recently ran the mri_glmfit-sim command to replicate a previous PhD student's result, and found out that his output and mine are different, although the code and input is exactly the same. The previous PhD student ran the code in 2022 April, and I ran it in 2023 October. This is the exact command I run mri_glmfit-sim --glmdir data/ses-0${timepoint}/${hem}_MM_${variable}_n31_ fwhm_src5trg5.glmdir/ --perm 1000 $sig abs --perm-resid --cwp 0.05 --2spaces; According to the log, the difference is in the simulation section, this is his log (2022.04.log) Starting simulation sim over 1000 trials mri_glmfit simulation done 42.124 this is mine (2023.10.log) Starting simulation sim over 1000 trials INFO: MRImask() using MRImaskDifferentGeometry() INFO: MRImask() using MRImaskDifferentGeometry() INFO: MRImask() using MRImaskDifferentGeometry() INFO: MRImask() using MRImaskDifferentGeometry() INFO: MRImask() using MRImaskDifferentGeometry().... mri_glmfit simulation done 27.9102 I attached log files for each to this email. I searched for what "INFO: MRImask() using MRImaskDifferentGeometry()" means in FreeSurferWiki, but I can't find any answer. Could you let me know if there are any updates about this command recently? 1) FreeSurfer version: freesurfer-Linux-centos4_x86_64-stable-pub-v5.3.0 2) Platform: Linux version 3.10.0-1160.21.1.el7.x86_64 ( mockbuild(a)kbuilder.bsys.centos.org) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-44) (GCC) ) Sincerely, Monami

lta_convert issue with ants Registration Matrix
by Yazdan Rezaee Jouryabi 18 Oct '23

18 Oct '23

External Email - Use Caution Dear all, Hi for checking registration i used fsl applyxfm on an Image(1)(Called Image.nii ) with specific Registration Matrice (Which we suppose to receive when we apply registration Methods) and Generate the "fsl_resampled.nii.gz" (Note: Image Orientations were LAS and in one other Experiment with also the same problem PSR) for our case i will attach the "fsl.mat" (Desired Matrix) using, fsl, freesurfer, and ants i got the correct results (let's call them "fslregistered.mat" and "freesurfer.mat" the converted lta to fsl-liked Matrix) Everything is OK till now But the converted lta-like and fsl-like matrix for ANTs (Which are called ants.lta, and ants.mat) using the lines below: - ConvertTransformFile 3 ./ANTS/ants_0GenericAffine.mat ./ANTS/ants.txt - lta_convert --initk ./ANTS/ants.txt --outlta ./ANTS/ants.lta --src ./Image.nii --trg ./fsl_resampled.nii.gz --ltavox2vox - lta_convert --inlta ./ANTS/ants.lta --outfsl ./ANTS/ants.mat --src ./Image.nii --trg ./fsl_resampled.nii.gz As All Results Images (Registered Image of all Methods) are aligned perfectly i think that there might be some issues with lta_convert Best Regards Yazdan Rezaee J *P.S. *" I've checked the one similar mail on this topic and the conclusion on that was about (sform, qform) incompatibility but the affine matrices of S-form and q-form are equivalent in my case."

External Email - Use Caution From what I can see, the freesurfer release 7 installers do not modify the shell init file, e.g., bashrc, and neither did the VM provided in the past with freesurfer 7.2.0 pre-installed have an entry with FS_DISABLE_LANG set in the bashrc file. - R.

NIH : Training in Advanced Statistical Methods in Neuroimaging and Genetics, April 15-26, 2024, Salt Lake City
by ROBERT CARY WELSH 16 Oct '23

16 Oct '23

External Email - Use Caution Hi everybody, We are pleased to announce that the application portal is still open for the NIH funded 2024 session of the course, “Training in Advanced Statistical Methods in Neuroimaging and Genetics”. We hope you pass this email and the associate flyer on to your local neuroimaging community. The course will start on Monday, April 15, 2024 and finish on April 26, 2024. We are happy to announce that the course is to be held in person, in Salt Lake City, Utah, United States at the University Guest House Conference Center. Our course also includes an ongoing continuing education portion. The course is an intensive 2-weeks, about 8 hours per day of a mix of lectures and hands-on computer labs. neurostatsbootcamp.org<http://secure-web.cisco.com/1lY-GvKYuvPetRR2S18eLjaUgPJfCtRozXBiQs2RBMuhfjF…> The course cost is $3000 (see scholarship information below), which includes hotel accommodations at the Guest House (arrival on April 14 with departure on April 26), breakfast, lunch, day time snacks, three dinners out as a group, and the planned evening activities. All course attendees will arrange for their own transportation to Salt Lake City. The course cost does include a daily pass to the Salt Lake City Trax light rail/commuter system. (Please note that the course instructors' effort is supported by the NIH grant thus avoiding that cost being passed on to the course attendees. This course is strictly not-for-profit.) Because of the limited size and advanced nature of the course, attendance is by application only – please make sure to fully read the website instructions. In general, applicants must be a US citizen, permanent resident, or with an appointment at a US institution, though we do have the ability to accommodate 3 to 6 individuals that do not meet this criteria. We anticipate the total class size to be between 22 and 25 students. There are opportunities for scholarships which can partially offset hotel accommodations. These are based on true financial need and you will be instructed how to apply if you are admitted to the course. We look forward to seeing you in SLC in 2024! The application deadline is Nov 1, 2023. Decisions around Dec 5th. For more information email us at neurostats(a)g.ucla.edu<mailto:neurostats@g.ucla.edu> or advancedstatisticscourse(a)utah.edu<mailto:advancedstatisticscourse@utah.edu> Robert and Anna ------------------------------ Robert Welsh, PhD Course Director, Training in Advanced Statistical Methods in Neuroimaging and Genetics rcwelsh(a)g.ucla.edu<mailto:rcwelsh@g.ucla.edu> robert.c.welsh(a)utah.edu<mailto:robert.c.welsh@utah.edu> Anna Docherty, PhD Associate Course Director, Training in Advanced Statistical Methods in Neuroimaging and Genetics anna.docherty(a)utah.edu<mailto:anna.docherty@utah.edu>
