PetSurfer: how to convert nopvc.nii.gz to a format like gtm.stats.dat?
by WONG Wan Wa 21 Aug '24

21 Aug '24

External Email - Use Caution Hi experts, As stated in the subject, how to convert "nopvc.nii.gz" generated by "mri_gtmpvc" to a format like "gtm.stats.dat"? Moreover, how to consolidate all "gtm.stats.dat"'s PVC uptake values of ROIs from different subjects in one spreadsheet? Is there any existing command to do that? Thanks, Angel

Re: [Freesurfer] Ubuntu 24.04 compatibility? (libc6 < 2.36, libncurses5)

External Email - Use Caution  We are aware that changes to the system libraries in Ubuntu 24 prevent installing packages, e.g., freesurfer, that otherwise install in Ubuntu 22.   The plan is to start development builds of Freesurfer on Ubuntu 24 after this years point release of Freesurfer.   Ubuntu 22.04 LTS was made generally available in April of 2022 with the standard 5 year support cycle from Canonical. - R.

If a 24.04 compatible release is not expected in the near future, do we know of any temporary fixes to get Freesurfer working? Or are we SOL on new servers for now?

Re: [Freesurfer] recon-all terminates at fix topology rh step

External Email - Use Caution  You’re using the 7.2.0 release from 2021 whereas the latest release is 7.4.1 from 2023.   Unless you have to stick with the older release because floating point math results could differ with a newer one, then you could try downloading and installing the 7.4.1 release from the links under “7.4.1 Release” at the top of the page, https://surfer.nmr.mgh.harvard.edu/fswiki/rel7downloadsOr try just running the subject that fails with the 7.4.1 release to see if it makes a difference. - R.

recon-all terminates at fix topology rh step
by Dong, Yilei 16 Aug '24

16 Aug '24

External Email - Use Caution Hi Freesurfer Developers, I have one particular subject that terminates at the Fix Topology rh step (screenshot of recon-all-status.log file below) until the job walltime runs out. This problem happens solely for this subject when I submit recon-all just for this 1 subject and also when I do batch submission with multiple other subjects. In batch submission, the 99 other subjects successfully go through recon-all's entire processing stream. For each recon-all job, we allocate 8G. Is there a way to troubleshoot this problem? [cid:fe218087-a1e3-4f1e-b1db-d3f5bf300cd2] Here is other information about my operating system & the freesurfer version. Please let me know if you need anything else! Freesurfer version: freesurfer-linux-centos8_x86_64-7.2.0-20210720-aa8f76b Platform: Rocky Linux release 8.8 (Green Obsidian) uname -a: Linux login01 4.18.0-513.24.1.el8_9.x86_64 #1 SMP Thu Apr 4 18:13:02 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux Recon-all log: see attached Sincerely, Yilei

Calculating gray matter volume and BPF from Samseg output
by Maaike Romme 15 Aug '24

15 Aug '24

External Email - Use Caution Dear all, For the past few days I have been trying to use the output from the Samseg tool to generate more volume metrics, such as gray matter volume. Unfortunately, I am not getting any output other than what I already get from Samseg. I tried running mri_segstats, but that also gave me the same volumes I already had. I was wondering if there is another tool within freesurfer to calculate these volumes for which I do not need to run the recon-all tool due to time constraints. Thank you in advance. Best regards, Maaike Romme
