Flip left-right orientation command
by Miguel Ángel Rivas Fernández 20 Mar '20

20 Mar '20

External Email - Use Caution Dear Freesurfer experts, Which command should I use to flip the left-right orientation of a T1 image?. Actually my image is in PIR orientation, I used the following command mri_info --orientation '/home/rmn/Desktop/study/E03/3d/coanat_E03.nii' *PIR* Thanks in advance, Best regards, -- *Miguel Ángel Rivas Fernández*

SPM Volumes on FSAVERAGE surfaces
by Ryne Nichols 20 Mar '20

20 Mar '20

External Email - Use Caution All, I'm having trouble getting good surface projections of SPM results. My SPM results come from SPM normalization -- which should be MNI152 space. I'm confused because fsaverage says it is in MNI305 space. I've tried a few commands, but the two that confuses me the most is: mri_vol2surf --mov SPMT_001.nii --mni152reg --trgsubject fsaverage --hemi lh --out lh_spm.mgh --projfrac-max 0 1 .1 Also the similar command: mri_vol2surf --mov SPMT_001.nii --reg $FREESURFER_HOME/average/mni152.register.dat --trgsubject fsaverage --hemi lh --out lh_spm.mgh --projfrac-max 0 1 .1 both give results in a wildly different place on the brain than they should be -- it flips the SPMT_001.nii in the Y direction. If I do mri_vol2surf --mov SPMT_001.nii --regheader fsaverage --hemi lh --out lh_spm.mgh --projfrac-max 0 1 .1 things are close, but nor exactly how they should be (it seems). Finally, if i use a surface that's in MNI152 space (cvs_avg35_inMNI152) things look the way they should, e.g.: mri_vol2surf --mov SPMT_001.nii --regheader cvs_avg35_inMNI152 --hemi lh --out lh_spm.mgh --projfrac-max 0 1 .1 thank you for any help you may provide! -ryne

Failed to load Surface lh.white
by Alexander Barnett 20 Mar '20

20 Mar '20

External Email - Use Caution Hello FreeSurfer Developers, I am trying to inspect the white matter gray matter surface to verify its accuracy as described in (http://freesurfer.net/fswiki/FsTutorial/ControlPointsV6.0) When I try to open freeview freeview -v 101/mri/brainmask.mgz \ -f 101/surf/lh.white:edgecolor=yellow I get an error that says it Failed to load Surface 101/surf/lh.white. The brainmask.mgz opens fine. When I looked in the /101/surf/ folder, I see lh.white.H, lh.white.K, lh.white.preaparc, lh.smoothwm, but there is no lh.white file. When I inspect the ReconAll table (https://surfer.nmr.mgh.harvard.edu/fswiki/ReconAllTableStableV6.0) I see that there is no step that creates ?h.white files in V6.0 (note: there is a step that will make lh.white in V5.3). How can I properly assess the white matter gray matter surface in V6.0? 1) FreeSurfer Version: freesurfer-i386-apple-darwin11.4.2-stable6-20170119 2) Operating system : MacOS High Sierra version 10.13.6 3) recon-all.log: see attached ReconAllTableStableV6.0 - Free Surfer Wiki<https://surfer.nmr.mgh.harvard.edu/fswiki/ReconAllTableStableV6.0> This table shows the recon-all steps for the stable, publicly released, version 6.0 of FreeSurfer (available here)..

Troubleshooting fix topology lh stall
by Hoang, Ricky 20 Mar '20

20 Mar '20

External Email - Use Caution Hello Freesurfer experts, I am trying to run recon-all to assess cortical thickness on a 3D FSPGR+C scan. The run keeps timing out during the fix topology lh step. I have looked at the resulting images and I am not sure whether I need to fix the white matter, add control points, or do something else entirely to fix the problem. The lh.inflated.nofix does not seem to have anything unwanted still attached and the lh.defect_label will not load. The lh.inflated.nofix does show some areas that have strands/spikes, which I think might be due to the gadolinium contrast. I wanted to ask for opinions on how to proceed. I have attached the recon-all.log. This is also a link to the output folder: https://drive.google.com/drive/folders/14fj1JAGAvuB-DpgLCxQwOXQ08u6-Vfvj?us… Thank you! Ricky

Permutation simulation produces unexpected results
by Purcell, Juliann 20 Mar '20

20 Mar '20

External Email - Use Caution Hi FreeSurfer Experts, I am running permutation simulations with several smoothing levels and cluster forming thresholds to evaluate the best parameters for our data, since there does not seem to be a consensus in the literature. However, I'm getting an unexpected result at only one smoothing/threshold level. I have run permutations (mri_glmfit-sim) at 0mm, 5mm, 10mm using the following thresholds: 1.3, 2.0, 2.3, and 3.0. Results of permutation at 10mm + threshold 1.3 were not as expected and did not line up with results at the other smoothing and threshold levels. I've re-checked that the command is correctly referencing the data and I've compared the th1.3 log file with the log files at the other thresholds. I could not find any differences that would cause the output of the permutation simulations to be so different between th1.3 and th2.0. There are no errors or failures in the permutation log files. I've searched the message board and didn't see any posts that related to this issue. Although it's possible that these are true results, I want to make sure there isn't a mistake on my end. Any help would be greatly appreciated! Below is information about my FreeSurfer version, platform, and the log files from the permutation simulations: 1) FreeSurfer version: freesurfer-Linux-centos6_x86_64-stable-pub-v6.0.0-2beb96c 2) Platform: Linux 3) uname -a: Linux c0135 3.10.0-1062.9.1.el7.x86_64 #1 SMP Mon Dec 2 08:31:54 EST 2019 x86_64 x86_64 x86_64 GNU/Linux 4) Perm sim log files: See attached logs for 10mm smoothing at threshold 1.3 and threshold 2.0 Best, Juliann Purcell, MSc Doctoral Candidate Medical/Clinical Psychology Doctoral Program University of Alabama at Birmingham Department of Psychology juliannp(a)uab.edu<mailto:juliannp@uab.edu>

Re: [Freesurfer] Operating System
by fsbuild 19 Mar '20

External Email - Use Caution Hello Stephanie, I already had 6.0.0 installed and did an incremental upgrade from 10.13 to 10.15, and did not run into any serious issues other than having to grant some permissions.   However, other older software already in /Applications may fail to run after the upgrade (which was the case after I did one upgrade). If you must upgrade, I suggest using Disk Utility to make a disk image backup of your entire boot or Macintosh HD partition so you can try to revert back using its restore function if necessary.  I've only put the upgrade on one machine because it is new Apple hardware that cannot run 10.13 or 10.14..  My advice generally is to always stay one revision behind the latest version of Mac OS - which right now would be 10.14 Mojave.  I don’t have or know of any software that only runs on 10.15 but does not run on 10.14.  So all my other machines that can still run 10.14 have not been upgraded. - R.
