Error Help

External Email - Use Caution Hi, I am new to FS and recently downloaded the package per instructions on your site. I set up the path and everything seems to be fine until I attempt to use any functions. I have searched for answers on this error, but I cannot seem to find anything so I am hoping you can direct me in fixing this. I am attaching the error log. I also tried to preprocess “bert” and got the same message. Thank you! Misque

Hippo subfields long
by Andrei Bieger 03 Jul '23

03 Jul '23

External Email - Use Caution Hello everyone, Quick question. After running the longitudinal recon-all pipeline, is it required to run all subjects/tps through the segmentHA before running the segmentHA_long? If no, since I already ran the segment_HA in a few subjects, if I stop and start running the segmentHA_long, will I have any trouble in overlaying output files? Thank you in advance!

trac-all with or without sub-thalamic nuclei segmentation
by Woo-Suk Tae 02 Jul '23

02 Jul '23

External Email - Use Caution Dear FreeSurfer developer. I successfully completed the tracula trac-all analysis using freesurfer 7.4.1. ThalamicNuclei.v13.T1.FSvoxelSpace.mgz images were obtained using segmentThalamicNuclei.sh, and trac-all analyses results were obtained using both set usethalnuc = 0 and 1 in the tracula config option. The tracts obtained from the two analyzes were similar in general, but slightly different in detail. Can you elaborate a bit more on what the usethalnuc option does to the results? Sincerely yours.

Excellent results from recon-all-clinical
by Michael Mc Laughlin 30 Jun '23

30 Jun '23

External Email - Use Caution Hi, I just wanted to say how impressed I am by the Freesurfer brain analysis software in general and to share some results of a comparison of the new *recon-all-clinical *option with various contrast types and resolutions. This is only one subject, a healthy 62 year old male, so it's a very small study indeed, but the recon-all clinical does a great job in finding the correct volume of gray and white matter with some very low resolution clinical MRIs with non-ideal contrast MRI settings. As you can see below, the T2 and T2 FLAIR gray and white volumes results with 0.72mm x 0.72mm x 6.5mm get very close to the correct volumes as measured by recon-all on the T1-MPRAGE scan. When I look at the actual detail of the slices it looks good too. Obviously it can't do magic and it has to basically "guess" where the information is completely missing when there is 6.5mm between slices. The cortex tissue volumes for the T1 headscout, which is 1.6mm cubic voxels and has very low contrast between white and gray is also very good, considering the data it has to work with. The standard recon-all is not designed to work with a clinical T1 SE scan and naturally, does a much poorer GM/WM segmentation job. Here are the results I got: [image: image.png] [image: image.png] [image: image.png] [image: image.png] So, well done to the whole Freesurfer crew and especially to the volunteers who devote so much time to this support list.

Longitudinal structural analysis in FreeSurfer ???
by Hamied Haroon 29 Jun '23

29 Jun '23

External Email - Use Caution Hello, I've run recon-all on patient T1s acquired at different timepoints after a neurological insult, in FreeSurfer v7.3.2 I want to analyse any change in the volume, surface area and average thickness of specific regions across time in each patient. Can I do this in FreeSurfer? Many thanks. Best wishes, Hamied Dr Hamied A Haroon, MSc, PhD, MInstP Research Associate in Biomedical Magnetic Resonance Imaging The University of Manchester

Re: [Freesurfer] Freesurfer Digest, Vol 232, Issue 12 - data not displayed

External Email - Use Caution I've re-enabled the gpu and updated the drivers, and now glxgears runs properly and freeview opens and displays data. I am still unable to click on anything in the popup editing menus though, and the cursor appears greyed out when hovering over these popup windows. I also tried MobaXterm with the same results. (Interestingly the device manager and Intel Driver and Support Assistant incorrectly suggested that the graphics driver was up-to-date and I had to manually search the Intel driver database to find the actual most current driver: 31.0.101.4502) Update: I have also had to switch to a new computer and am running Ubuntu 22.04.2 with freesurfer-linux-ubuntu22_x86_64-7.4.1-20230614-7eb8460 through wsl2 Thanks, Haley
