Unexpected cortical expansion in the anterior cingulate
by Gordon, Brian 25 Mar '24

25 Mar '24

External Email - Use Caution I saw this paper making the rounds recently (https://secure-web.cisco.com/1xpFxsKoB351lR8nLgcY1jLc9MKM9SFg22L-Gj-yGOtM9a…) arguing that there are some areas where the cortex appears thicker with advancing Alzheimer Disease. The paper points towards prior publications from my own group which studies autosomal dominant AD where similar effects were found albeit did not reach significance. I've also seen this unexpected directional reversal in other cohorts. For aging I've seen it as far back as 2004 (https://secure-web.cisco.com/1exfvo1PFoqzlNRA3kd-j6t_3mH_q9fK-YbuHkw-gMEwFD…) Have others seen this? I don't tend to think of their being true increases in thickness in neurodegenerative diseases, although I guess it could have occurred. I've always wondered if instead it had to do with some sort of bias or quirk that is coming into play when you have large displacement of this region due to expanding ventricles. I was just curious if other groups had seen this and if so with what disorders. ________________________________ The materials in this message are private and may contain Protected Healthcare Information or other information of a sensitive nature.

nu_correct: Command not found error
by Dong, Yilei 25 Mar '24

25 Mar '24

External Email - Use Caution Hi Freesurfer support, Recently, I submitted a script to run recon-all on 100 mri images on UCSD's computing cluster, called EXPANSE. I get an error file that says "nu_correct: Command not found. FREESURFER: Undefined variable." The sample error file and the output file I have attached for one of the subjects are recon-all-slurm.29376886.exp-5-44.err & recon-all-slurm.29376886.exp-5-44.out respectively. The script I used to submit the job via slurm is called recon-all-slurm.sb. I googled the error and found that someone else who had a similar situation did not source their Freesurfer environment correctly. Would this be the same thing for us as well? The main thing for us is Freesurfer/7.2.0 already has been available as a module for us on EXPANSE. Sincerely, Yilei

recon-all mris_preproc error: Cannot find surf/lh.w-g.pct.mgh

External Email - Use Caution Hello, I have a longitudinal dataset where each participant was scanned twice over the course of 5 months. I have been following FS's Longitudinal Tutorial <https://secure-web.cisco.com/1cEj8JFOeCVl553obrTrsTW9AP-8Qv0LHSe3IerGFGTmaP…> .

Using orig.mgz or T1.mgz as input to recon-all
by Jeong Yeon Kang 25 Mar '24

25 Mar '24

External Email - Use Caution Hello FreeSurfer Developers, I am attempting to run recon-all on a group of subjects. We no longer have the raw T1s. Instead, we have their orig.mgz and T1.mgz files from a previous run of freesurfer. We wish to rerun recon-all using their orig.mgz or T1.mgz as inputs, using FreeSurfer5.3. What would be the best way to go about this? 1. I ran recon-all normally, with orig.mgz as the input file. It ran to completion, but some files are missing from subdirectories. I am not sure if the outputs are correct, and comparable to other datasets that have freesurfer outputs that used raw T1s. 2. I converted orig.mgz to orig.nii.gz using mri_convert, and used orig.nii.gz as input to recon-all. This also ran to completion. However, because I cannot compare this output to any "true" output, I am unsure if the outputs are correct, and is the same as using a raw T1 as input. 3. I considered manually starting the recon process from T1.mgz (organizing subdirectories manually, inserting T1.mgz and orig.mgz into /mri, and starting autorecon2. I am unsure if this is best, as I am missing nu.mgz, which is an input file in the first step of autorecon2. Please let me know what you think, and which method you think would be closest to using the raw T1s. I've searched the list and it seems that no one has attempted a similar task. Thank you. Sincerely, Melody

What do the stats files tell us?

External Email - Use Caution Hello, So I ran FreeSurfer to get numeric data from MRI images and got these files under the stats page. [image: Screenshot 2024-03-18 144107.png] Do you know what each file tells us about our MRI images such as the lh.aparc.DKTatlas.mapped, lh.BA_exvivo.stats, lh.BA_exvivo.thresh, lh.curv, lh.w-g.pct, and wmparc.DKTatlas.mapped files? Thanks, Vivek Kandasamy
