Systematic difference in volume between baseline and longitudinal pipelines
by Sandhitsu Das 12 Nov '24

12 Nov '24

External Email - Use Caution It seems the original posting did not go through likely because it had an attachment. Here it is again. I have seen some threads from a few years ago discussing differences in thickness, and we see this in volume as well (v6). I had an attached plot for left caudate volume in the original post which showed larger volumes in the long pipeline. I understand it is not meaningful to compare the base and long pipeline values, but I would like to understand the reasons behind it, particularly the directionality of the bias seen in the scatter.

Re: [Freesurfer] mri_convert: Command terminated by signal 9
by Huang, Yujing 11 Nov '24

I’m not sure what happened. I see you have three mri_convert runs. Each time it behaves differently. Can you try the following without invoking your makefile? 1. install Freesurfer 7.4.1 2. register and get a license file, put it in your home directory. set FS_LICENSE environment variable to point to the license file. 3. source Freesurfer 7.4.1 4. set SUBJECTS_DIR 5. run mri_convert command (use ‘which mri_convert’ to see where the command is located) Yujing From: Noah Reardon <nreardon(a)umich.edu> Sent: Monday, November 11, 2024 3:09 PM To: Freesurfer support list <freesurfer(a)nmr.mgh.harvard.edu> Cc: Jeffrey Neal <jsneal(a)umich.edu>; Huang, Yujing <YHUANG43(a)mgh.harvard.edu>; fsbuild(a)contbay.com Subject: Re: [Freesurfer] mri_convert: Command terminated by signal 9 External Email - Use Caution Hi all, Please see the attached screenshot demonstrating how mri convert is getting deleted when we try to use it.

Hello Freesurfer Developers, I am working with a lab who is trying to use freesurfer command: Make recon-all -k which fails with: command terminated by signal 9. If we try re-running it, we have to remove the folder created by it before we can re-run the command again, which will then report missing files such as mri_convert along with a few others that magically disappear from the bin folder. Everything works on version 7.1.1 as it should but they want to use 7.4.1 to make use of some more functions and version 7.4.1 is the version we are having the issue with.

recon all data for classification between groups !
by JM 11 Nov '24

11 Nov '24

External Email - Use Caution Dear FS experts, I have longitudinal data: Three time-points [T1-T3] with an interval of about 6 months between T1 and T2 and 6 months between T2 and T3 from a control group as well as from a clinical group (again three time-points [T1-T3] with an interval of about 6 months between T1 and T2 and 6 months between T2 and T3). Sample sizes are: - For control group: 48 (for T1), 36 (for T2) and 33 (for T3) - For clinical group: 38 (for T1), 33 (for T2) and 31 (for T3) I was wondering if it's fine to consider and combine three time-points within each group as independent samples for classification purposes (i.e., N = 117 (48+36+33) for the control group and N = 102 (38+33+31) for clinical group) between the two groups (based on brain morphometry measures). If so, I was wondering whether the recon-all should be done in the longitudinal way ( https://secure-web.cisco.com/17EJvCDRair_uWYfmRy5gjgpT3fQihw2Qeo96vmyp96h9n…) i.e., making it unbiased towards a specific time-point, OR, the recon all should be run cross-sectionally so that we can keep all the time-points independent from each other. Any detailed explanation/justification would be really helpful. Also, I would greatly appreciate the response at earliest convenience. Thanks, M

NextBrain - CUDA out of memory error
by Boa Sorte Silva, Narlon 08 Nov '24

Hi there, I am playing around with NextBrain with a dataset of individuals with large white matter lesions, and I am noticing that in 10% of the cases NextBrain fails to finish due to a OOM error, such as this: RuntimeError: CUDA out of memory. Tried to allocate 1.08 GiB (GPU 0; 31.73 GiB total capacity; 28.54 GiB already allocated; 1.00 GiB free; 30.30 GiB reserved in total by PyTorch) If reserved memory is >> allocated memory try setting max_split_size_mb to avoid fragmentation. See documentation for Memory Management and PYTORCH_CUDA_ALLOC_CONF I have tried to adjust the max_split_size_mb parameter to circumvent the problem (PYTORCH_CUDA_ALLOC_CONF=max_split_size_mb:512) but it is still failing for some individuals. Do you guys have any inputs about how to deal with this? For context, I am using a cluster with two 32GB GPUs with additional 10 CPUs. Thanks! Nárlon External Email - Use Caution

MD5 mismatch on one release

External Email - Use Caution Hello FreeSurfer Developers, Firstly, Thanks for your great work. Two different releases have the same MD5 hash "1f107c22eb75821e1aa46b55a6eb8189", namely freesurfer_ubuntu20-7.4.0_amd64.deb (Correct one) freesurfer_ubuntu20-7.3.2_amd64.deb (MD5 b2d0f8e6285f4a8da72d008a6390a7fe) The second one needs to be checked. Best regards

Synthstrip error in FS v. 8.0.0 beta
by Raikes, Adam C - (adamraikes) 07 Nov '24

07 Nov '24

External Email - Use Caution Hello Developers, I was attempting to test out the beta version of 8.0.0 and I recognize that this is on-going development. I installed it in a Singularity image running Ubuntu 22.04. Getting recon-all to run at all requires setting an environmental variable (FS_ALLOW_DEEP=1), which I did and recon-all launches. However, it crashes very quickly. In short, orig/001.mgz is created and then it immediately attempts to run mri_synthstrip on orig.mgz, which does not exist yet. See attached logs. Adam C.
