Thalamic nucleus segmentation 3D export
by Paulk, Angelique C.,PHD 10 Oct '22

10 Oct '22

Hello, I apologize if this has been answered before though I could not find this specific information in the archives. We are hoping to export the Thalamic nuclei segmentations to 3D volumes outside of Freeview/Freesurfer (e.g. .stl or other options) to perform a number of calculations in python or Matlab or visualize in Blender. I have been able to use 3DSlicer and get segmentation and 3D renders by importing the "aparc.DKTatlas+aseg.mgz" file and export .stl files in 3DSlicer, but, when I import the "ThalamicNuclei.v12.T1.FSvoxelSpace.mgz" file, it is only showing the entire thalamus as a mask in 3DSlicer though the nuclei are segmented in Freeview. Is there another type of export from FreeSurfer that would allow this type of saved volume/surface export? Thank you for all your help, Angelique

Hemisphere in Yellow
by Jun Yeon Won 10 Oct '22

10 Oct '22

External Email - Use Caution Dear Freesurfer experts, I am running a linear regression analysis and found a significant result showing below (cache.th20.abs.sig.cluster.summary file). [image: image.png] I ran the below script to get this result. Right hemisphere was focused for this analysis. mri_glmfit-sim --glmdir rh.thickness.10.glmdir \ --cache 2 abs \ --cwp 0.05 But, when visualizing the cache.th20.abs.sig.cluster.mgh file, it shows below - the hemisphere is in yellow. [image: image.png] The below is a visualization of sig.mgh. The underlay should be gray but I am not sure why the underlay looks yellow when overlaying the thresholded result. [image: image.png] I saw somebody posted the same issue here ( https://secure-web.cisco.com/1OHcN_bRSEDk0roNAjIAfufCwrh4xf7rzgQtoclY3flDVp…) but I was not able to find the solution from here. Could you please let me know what is an issue and how to resolve this? Best, Jun

Re: [Freesurfer] mkdir: /Applications/freesurfer/7.3.2/subjects/sub01: Permission denied

External Email - Use Caution Hello Padma, The freesurfer installation under /Applications on MacOS, like most applications installed there, does not expect users to write their own data into what is installed there.  Or the example subjects that  are part of the freesurfer installation - pointed to by the environment variable SUBJECTS_DIR - is not meant to be written to with user data. So just change SUBJECTS_DIR to point to a directory where you have normal write permissions.  One location would be your home directory, e.g., $ echo $HOME /Users/padma $ cd $HOME $ mkdir subjects $ export SUBJECTS_DIR=$HOME/subjects $ echo $SUBJECTS_DIR /Users/padma/subjects Then put your subjects data there to process, etc.Here are some links with some additional info,https://secure-web.cisco.com/1whAZMfyHZ4FLyVo5f2kazK_sVsLOEt4UrO4idC_8… https://secure-web.cisco.com/1J0Gr93Wou3vnAj2gdII49F94CdlmxnssGDtUMKvrvolLz… R.
