seed point on the CC and Pons
by Jie Zhao 09 Oct '20

09 Oct '20

External Email - Use Caution Hello Freesurfer Experts I am trying to set the correct seed point to cutting the corpus callosum and pons for a macaque subject. It is aimed to remove the brainstem and cerebellum, right? My command line is : recon-all -s monkey2 -autorecon2-inflate1 -noaseg -cc-crs 100 85 112 -pons-crs 99 105 80 The output result is sucessed without errors, but the wm.mgz still include the brainstem and cerebellum in my freeview. I am wondering whether my coordinate used above command is correct ? It is from the Cursor on the right of wm in attached pictures. I know here need talairach coordinate and which one on the Cursor is correct ?Sorry for my ignorance. Any suggestions will be appreciated! Kind Regards Jie

Seed region in anatomical data for resting state fMRI data
by Kim, Gwang-Won 09 Oct '20

09 Oct '20

Hi there, I obtained a seed region (left superior frontal)from anatomical data to process resting state fMRI data as follows: fcseed-sess -o lh.SFC.dat -segid 1028 -s session -fsd rest. I wonder if what the seed region is the left superior frontal was correct. Question1: Can I display the lh.SFC.dat as MR image (anatomical image) using Freeview? I'd like to obtain ROI region as a seed region from anatomical data to process resting state fMRI data. Question2: How do I make the seed region if I use 8-mm radius spheres centered on a MNI coordinate [x=20, y=20, z=20] as the seed region. Thanks, Gwang-Won

Matlab Matlab Runtime issue
by Wei Shao 08 Oct '20

08 Oct '20

External Email - Use Caution Hello, Freesurfer team My name is Wei Shao, FS user, I have a few questions regarding the Matlab package and the hippocampal subfield function with FS. I have followed the instruction from the website to install Matlab, sue the fs_install_mcr R2014b (Oct 01, 2020 14:41:05) Exiting with status 0 (Oct 01, 2020 14:41:05) End - Successful. Finished MCR v84 (R2014b) already exists in /usr/local/freesurfer/7.1.0-1 do you want to reinstall? [y/n] exiting without install *However*, when I try to use the hippocampal seg command: *segmentHA_T1.sh, it gives me this error* ERROR: cannot find Matlab 2014b runtime in location: /usr/local/freesurfer/7.1.0-1/MCRv84 The hippocampal/amygdala and brainstem modules require the (free) Matlab runtime. You will need to download the Matlab Compiler Runtime (MCR) for Matlab 2014b. To do so, please run the following commands (you might need root permissions): LINUX: cd /usr/local/freesurfer/7.1.0-1 curl " https://surfer.nmr.mgh.harvard.edu/fswiki/MatlabRuntime?action=AttachFile&d…" -o "runtime2014b.tar.gz" tar xvf runtime2014b.tar.gz Even after I did this as the following, it still gave me the same response when I tried segmentHA_T1.sh. Could you tell me how to fix this? Thanks! Best, Wei

white matter surface extends too much into the cortex
by Caroline Chwiesko 07 Oct '20

07 Oct '20

External Email - Use Caution Dear Freesurfer team, when checking the output after recon-all i am having the issue that the white matter surface extends too much into the cortex. I observe this in most of my subjects (mostly in the posterior part of the brain) so it seems to be a systematic issue. I found in the archive that others had a similar problem and were asked to upload one subject to get a recommendation on how to change certain default parameters in recon-all to fix this problem. I was wondering if I could also upload a subject and get a recommendation for my data set on how to fix this issue ? Thank you very much in advance! Carolin
