bug in pial placement with FLAIR images
by Douglas N. Greve 16 Dec '22

16 Dec '22

I recently found a bug in the pial placement refinement with FLAIR images (recon-all -flair ...) that affects version 7.{0,1,2,3}. This bug caused the pial surfaces to not extend nearly far enough. It has been fixed in the development version of FS and so will be in future versions. If you want to access the fix before then, create a $SUBJECTS_DIR/global-expert-options.txt with this line PlaceMMPialSurf --mm_min_inside 50 --mm_max_inside 200 --mm_min_outside 10 --mm_max_outside 50 sorry for any inconvenience doug

regress out signal
by Mingyang Xia 16 Dec '22

16 Dec '22

External Email - Use Caution Dear Freesurfer expert: After I used ' fcseed-config' to get wm.dat and csf.dat, how could I get the signal of each voxel that regresses out the nuisance. I do not want to do the analysis. I just want to get the signal after regressing out nuisance. Thank you Mingyang Xia

External Email - Use Caution I have resolved by eliminating the option -nowhiten It looks like the anatomical analysis is out of sync with the functional analysis. Is is possible that you ran the functional analysis, then edited the subject, then tried to rerun the analysis? If so, try running preproc-sess with -force to redo all the preprocessing.On 12/1/2022 12:45 PM, std...(a)virgilio.it wrote: > External Email - Use Caution I would extract the rs-fMRI timeseries from Yeo’s Network components.

Use annotation for edgecolor in freeview
by Chris Adamson 16 Dec '22

16 Dec '22

External Email - Use Caution Freesurfer, Is there any way of using an annotation file to set the edge color for a surface so that the annotation labels are visible in the 2D slice view?

Re: [Freesurfer] Creating and analyzing combined ROIs, combining different FreeSurfer versions
by Trolle, Carl 15 Dec '22

15 Dec '22

Ok, thank you! Would the command to add the label to glmfit then be --label file.label or --label fsaverage/label/file.label? I found different suggestions in the mail_archives, with some explicitly specifying the fsaverage-path and some not. Is it possible to then run permutations as per the FS permutation tutorial with the output from above (after including the --eres-save flag in the mri_glmfit command)? Kind regards, Carl On 12/12/2022 6:14 PM, Trolle, Carl wrote: > Thank you for the reply, > > 1.

Sorry didn't quite understand this part. > Nope, once you have the ROI you want in the native subject space, just use it, no need to go to fsaverage at all. That was only for if you were going to draw your own label. Instead of drawing it on 10s or 100s of subjects you would draw it once on fsaverage then transfer it to all your subjects.

SynthSR and SynthSeg
by Yoonho Hwang 15 Dec '22

15 Dec '22

External Email - Use Caution Dear FS developers, Hi, I'm Yoonho. I know that new features, such as SynthSeg, SynthStrip, segment_subfields (beta version), etc, based on deep learning have been added after the FreeSurfer 7.3.2. Here I have questions (I read papers related to SynthSR, SynthSeg, SynthStrip, segment_subfields). *1. Can I use the SynthSR functions o**nly by FreeSurfer development (dev) version (https://secure-web.cisco.com/1ps3QL5XW2qOOptSgD9TqOIsWnQJlFGcz9nxZ59lvSiCbI… <https://secure-web.cisco.com/1ps3QL5XW2qOOptSgD9TqOIsWnQJlFGcz9nxZ59lvSiCbI…>)**?* *2. When T1WI data are processed with recon-all, are SynthSR and SynthSeg functions included in the "recon-all" process pipeline? If not, are SynthSR and SynthSeg processed separately?* *3. Is the recon-all process included in SynthSeg and SynthStrip by default?* *4. When I process T1WI data with Freesurfer dev version, is it installed based on the new version in HPC per version update for freesurfer?* *5. I think using SynthSR and SynthSeg functions can solve the Harmonization issue (data acquired from other manufacturers (Siemens, GE, Philips), protocols (FSPGR, MPRAGE, etc), and other sites). What do you think about that?* *6. In lh.w-g.pct.stats file, I know that "Mean" means GWC (gray/white matter contrast), which is (100/0.5)*[(white matter intensity - gray matter intensity)/(white matter intensity + gray matter intensity)], as far as I know, I want to know in detail whether the 0.5 term should be omitted and 100 is to appear as a percentage.* Thank you for reading my long question Please let me know if there is anything you don't understand. Looking forward to your feedback. Thank you very much. Sincerely, Yoonho --

High Resolution Freesurfer Error
by Brooklyn Wright 15 Dec '22

15 Dec '22

External Email - Use Caution Hi there 🙂 I am running into repeat difficulty with reconstructing ultra-high resolution T1w .nii images (0.25mm^3 voxel size). These have been submitted to rigorous preprocessing steps and I use hires flags and expert preferences however all of my attempts' output has some part of the brain missing as if it got two-thirds of the way through and then gave up. Have you got any suggestions on how to tackle this? Kindest, Brooklyn.
