Thalamic nuclei segmentation - PuM nucleus mis-segmentation?
by Gronow, Franziska 10 Mar '21

10 Mar '21

External Email - Use Caution Dear Eugenio, thanks for your response. I wasn't sure whether .mgz files contain patient information so I had to clarify that. It would be great if you could take a look on the affected cases. I could send you norm.mgz files of one or more subjects. Can I send them directly via email or do you prefer dropbox? Thanks again!

The more slices the better __ Maybe it would be possible to share norm.mgz (which is skull stripped and thus deidentified) and the segmentation? Or maybe even crop norm.mgz around the thalami with Freeview?

Re: [Freesurfer] mris_sphere error: terminated by signal 9
by fsbuild 09 Mar '21

External Email - Use Caution Since you are running in VirtualBox, you should try clicking on the SETTINGS wheel in the VirtualBox application window, then in the pop-up window click on SYSTEM, and look at the amount off memory you have allocated to the VM.   I would try and increase the amount to 10 - 16G of RAM from the system, but also avoid giving it much more than 1/2 of the total memory available on your host system.  VM’s sometimes will not start up if you give them too much RAM.  Similarly, for the number of processors you allocate from the host system, i.e., you might not want to give it more than 1/2 depending upon what else is going on with the machine besides running VirtualBox.

TRACULA preprocessing errors: cannot create dwi_orig_las.nii.gz
by Rita Vieira 08 Mar '21

08 Mar '21

External Email - Use Caution Dear FreeSurfer experts, I am a new user of FreeSurfer and I am trying to apply TRACULA to my data. However, I am stuck in the pre-processing part. I have the following error at the end: ERROR: Transform file should be eddy_correct/eddy log file or .mat file But, the problem starts early because it cannot create the dwi_orig_las.nii.gz file. Also, the bvecs.norot is filled with zeros. I checked the bvals and bvecs file and they follow the format required by TRACULA. In attachment, you can find the configuration and trac-all.log files. Thanks in advance! Rita

Supporting older versions of FreeSurfer (5.3) on newer OSs
by Tobias, Malcolm 08 Mar '21

08 Mar '21

External Email - Use Caution All, We're setting up a new cluster (based on CentOS 8) but have many users that still want to run older versions of FreeSurfer (5.3 and 5.3-HCP). We're hitting a perl error which appears to be a known issue with newer versions of Perl: [mtobias@login02 mri]$ mri_nu_correct.mni --n 1 --proto-iters 1000 --distance 50 --no-rescale --i orig.mgz --o orig_nu.mgz /mnt/beegfs/scratch/mtobias/mri /export/freesurfer/freesurfer-5.3.0-HCP/bin/mri_nu_correct.mni --n 1 --proto-iters 1000 --distance 50 --no-rescale --i orig.mgz --o orig_nu.mgz nIters 1 $Id: mri_nu_correct.mni,v 1.18.2.1 2013/01/09 21:23:42 nicks Exp $ ... Can't use 'defined(@array)' (Maybe you should just omit the defined()?) at /export/freesurfer/freesurfer-5.3.0-HCP/mni/bin/nu_estimate_np_and_em line 165. nu_correct: crashed while running nu_estimate_np_and_em (termination status=65280) ERROR: nu_correct One fix suggested for Ubuntu users is to install an older version of Perl. While we've tried that on our system, it seems the perl scripts are hard-wired to use /usr/bin/perl: [root@mgt bin]# head -1 nu_estimate_np_and_em #!/usr/bin/perl -w So without replacing the system perl on every system in the cluster, is anyone aware of any other work-arounds for this issue?

Extracting individual activation values in FSFAST
by Fang, Angela,Ph.D. 08 Mar '21

08 Mar '21

Hello Freesurfer community, I would like to extract individual brain activation values in specific clusters emerging from an FSFAST group analysis that tested a certain contrast during a task, to be entered as predictors in a linear regression model. Is it possible to obtain these individual level activation values using commands in FSFAST? Or is it possible to extract individual level effect sizes from this group analysis from the contrast effect size files? Thanks so much for your help!

Unknown label interpretation in Desikan-Killiany atlas
by Yu-Wei Chang 08 Mar '21

08 Mar '21

External Email - Use Caution Dear FreeSurfer Support, I am writing this letter to inquire about the labeling system for Desikan/Killiany atlas. Specifically, we would like to ask whether the label "CTX_LH_UNKNOWN_SUVR" shall be included for the anaylsis or not. -- As far as we are concerned, we found the related information in archives of FreeSurfer support: https://secure-web.cisco.com/1pj3f15nIYncSqPaxZxKxOkPY68taDPj-zLxvjs3pwd01d… unknown volume means it's not part of the cortex (usually on the medial wall where the surface crosses things like the callosum, the thalamus, the ventricles, etc...) -- It appears that the value of this label is meaningful in our current analysis. Therefore we would very much appreciate if you can give us some suggestions or elaboration about the unknown label in freesurfer, and how to interpret it. Sincerely, Yu-Wei **************************** Yu-Wei Chang 張育瑋 Doctoral student UNIVERSITY OF GOTHENBURG Department of Physics Gothenburg, Sweden
