Convert mgz to nii
by Hua, Jessica 31 May '20

31 May '20

External Email - Use Caution Hi FreeSurfer experts, I would like to convert my .mgz parcellation file to a .nii file to be used in DTI analyses. How would I convert my participant's aparc+aseg.mgz file to a .nii file?

Longitudinal study dimension mismatch
by KennethSPrice 30 May '20

30 May '20

External Email - Use Caution Hello Freesurfers! I am running a recon-all -long study and one of my subjects is giving me trouble. The brain segmentation volume for tp2 is greater than tp1. The scans were taken from the same machine with the same parameters, but the dimensions are mismatched: Volumes differ in dimension v1dim 512 512 32 1 v2dim 560 560 30 1 I am worried that dimension mismatch is causing an error in brain volume estimation. I have tried reslicing v1 to v2 dimensions but freesurfer did not like it. Would a dimension mismatch lead to significant volume differences, and is there any work around? \ Thanks, Ken Sent with [ProtonMail](https://protonmail.com) Secure Email.

Cannot execute Binary file
by Graduate Imaging 30 May '20

30 May '20

External Email - Use Caution Hi, I recently downloaded fspalm, mri_surfcluster and mri_volcluster for freesurfer v6.0 from ftp://surfer.nmr.mgh.harvard.edu/pub/dist/freesurfer/6.0.0-patch/PALM/ and added them to the freesurfer/bin folder (had to replace the previous versions of mri_surcluster and mri_volcluster) and ran chmod a+x on all three to make them unix executable files. When I ran fspalm the permutation part of the command worked however when it reached the mri_surfcluster command it produced the following error in terminal "-bash:/Applications/freesurfer/bin/mri_surfcluster: cannot execute binary file" I'm running freesurfer on a MacOS system, are these the correct versions of the files I should be using? Thanks

External Email - Use Caution Hello, The files mri_surcluster and mri_volcluster that you downloaded are patched versions for the linux distribution, so they won’t run on MacOS. But you should need to download them as they should already exist in the MacOS freesurfer distribution.  Or you should already have them under ./freesurfer/bin ($FREESURFER_HOME/bin in the freesurfer shell/environment) - under wherever your MacOS installation of freesurfer lives.   If you need to, you can download the freesurfer 6 MacOS distribution from https://surfer.nmr.mgh.harvard.edu/fswiki/rel6downloads, install it on your own Mac and get those files. - R.

AAL parcellation for Freesurfer
by Bastian Cheng 29 May '20

29 May '20

External Email - Use Caution Dear all, does anyone know if there is a surface parcellation file based on the AAL for freesurfer? I am aware that I could recon-all the MNI brain and project the atlas on the surface. (but maybe someone already did that) I spend some time googeling this, but haven't found it, therefore my question. all the best, Bastian <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campai…> Virenfrei. www.avast.com <https://www.avast.com/sig-email?utm_medium=email&utm_source=link&utm_campai…> <#DAB4FAD8-2DD7-40BB-A1B8-4E2AA1F9FDF2>

mri_cnr label flag
by Pradyumna Bharadwaj 29 May '20

29 May '20

External Email - Use Caution Hi, I had a question about the -label flag in mri_cnr. 1) When you do not use the -label option and just use the following command: mri_cnr $FREESURFER_HOME/subjects/bert/surf $FREESURFER_HOME/subjects/bert/mri/norm.mgz The output is as follows white = 96.6+-6.0, gray = 75.7+-13.5, csf = 55.3+-16.6 gray/white CNR = 1.983, gray/csf CNR = 0.907 lh CNR = 1.445 white = 96.4+-6.0, gray = 76.0+-13.3, csf = 55.6+-16.2 gray/white CNR = 1.952, gray/csf CNR = 0.943 rh CNR = 1.448 total CNR = 1.446 2) When you add -label $FREESURFER_HOME/subjects/bert/label/lh.cortex.label $FREESURFER_HOME/subjects/bert/label/rh.cortex.label to the first command, you get different (lower) cnr values. white = 96.6+-6.0, gray = 73.1+-18.9, csf = 50.8+-20.5 gray/white CNR = 1.389, gray/csf CNR = 0.644 lh CNR = 1.016 white = 96.4+-6.0, gray = 73.4+-18.8, csf = 51.0+-20.3 gray/white CNR = 1.353, gray/csf CNR = 0.652 rh CNR = 1.002 total CNR = 1.009 How is the lh.cortex and rh.cortex label changing the CNR computation? Any inputs or thoughts on this matter are greatly appreciated! Thanks, Prad

Fwd: Error in Monte Carlo simulation
by behzad sorouri khorashad 29 May '20

29 May '20

External Email - Use Caution TO: freesurfer(a)nmr.mgh.harvard.edu SUBJECT: Error in Monte Carlo simulation: Error running mri_surfcluster Hello FreeSurfer Developers, I'm attempting to run a longitudinal analysis on structural T1 images for a sample, as described on the freesurfer wiki tutorial ( https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/LongitudinalTutorial) For post processing data, i used qdec option. However, when i want to use the monte carlo correction I receive the following Error: Error in Monte Carlo:Error in running mri_surfcluster If I change the number in /qdec/untitlted/fwhm.dat to the fwhm i have chosen in my analysis, the error is solved. But I wonder whether this is correct way to solve this error or not. I've searched the list and no similar errors have been reported. Does anyone have any thoughts on how to trouble-shoot this one? Also, Ive attached the error in the terminal in case it's of any use. 1) FreeSurfer version: freesurfer-Darwin-OSX-stable-pub-v6.0-2beb96c 2) Platform: OS X ElCapitan verson 10.11.6 Thanks for your help Yours Behzad

Re: [Freesurfer] ERROR: mri_fill: could not find any points where lh and rh wm are nbrs
by Marina Fernández 28 May '20

28 May '20

External Email - Use Caution Hi Bruce, The talairach transform is reasonable and the aseg segment the cc correctly. I run with freesurfer dev version the same command (recon all -autorecon-2wm -subjid post_006) and now I have more information about what could be the problem. The output of the terminal (that you can see below) says that there is a vertex in the curv file of each hemisphere that has one vertex number that it is not expected. When I open the curv file in tksurfer there is a 0 in these positions. Maybe this output can be useful to help me solve the problem. What do you think I should do?

fs_install_mcr error
by AmirHussein Abdolalizadeh 28 May '20

28 May '20

External Email - Use Caution Hi all, I have installed FS7 (centOS8 version) on ubuntu 18.04. I try to install MATLAB runtime but it gives an error when I type "fs_install_mcr R2014b": Archive: installer.zip End-of-central-directory signature not found. Either this file is not a zipfile, or it constitutes one disk of a multi-part archive. In the latter case the central directory and zipfile comment will be found on the last disk(s) of this archive. unzip: cannot find zipfile directory in one of installer.zip or installer.zip.zip, and cannot find installer.zip.ZIP, period. Since I suspected it might be an access issue, I have used chmod -R 777 on my FreeSurfer installation category. Also, using "sudo" before "fs_install_mcr" causes the bash not to recognise fs_install_mcr command. Any suggestions? Bests, Amir
