External Email - Use Caution Dear FS experts, I am looking at the relationship between the cortical thickness and a behaviour measure, while controlling for the effects of age and gender. In this analysis, I am using CT_AT.fsgd, contrast_pos.txt and a contrast_neg.txt. GroupDescriptorFile 1 Title Autistictraits Class AT Variables Age Gender AT Input Con_P001 AT -4.142 -0.428 21 Input Con_P002 AT -8.142 -0.428 31 My separate two contrast files: Contrast_pos.txt 0 0 0 1 Contrast_neg.txt 0 0 0 -1 mri_glmfit --y lh.thickness.AT.10B.mgh --fsgd CT91_4.fsgd doss --C Contrast91_pos.txt --surf fsaverage lh --cortex --glmdir glmdirlhposlat.glmdir mri_glmfit --y lh.thickness.AT.10B.mgh --fsgd CT91_4.fsgd doss --C Contrast91_neg.txt --surf fsaverage lh --cortex --glmdir glmdirlhneglat.glmdir mri_glmfit-sim --glmdir glmdirlhposlat.glmdir --cache 1.3 pos --cwp 0.05 mri_glmfit-sim --glmdir glmdirlhneglat.glmdir --cache 1.3 neg --cwp 0.05 By changing the commands appropriately, I am looking at the right hemisphere too. Can anyone please help me to clarify, if I am applying the command lines correctly? Any sort of help would be very much appreciated.

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

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.

longitudinal FreeSurfer help
by Swati Rane 17 Mar '20

17 Mar '20

External Email - Use Caution Dear FreeSurfer experts, I simply do not understand the LME setup for longitudinal analyses. Here is what I have: 3 groups each with variable longitudinal data (in terms of umber of time points and interval between timepoints). I am interested in detecting if the rates of longitudinal atrophy in each of the 3 groups and whether it is significantly different between the 3 groups. 1. My Qdec file contains: fsid, fsid_base, time, age, group, gender 2. I read in the relevant files with (output of surf2surf, lh.cortex, lh.sphere) 3. I read the Qdec file removed the first column, obtained the subject IDs, keep numerical data and get a sorted ‘M’ matrix 4. X=[intercept time grp1 time*grp1 grp2 time*grp2 grp3 time*grp3 age@timepoint1 gender] 5. After that, should I use voxel wise mass-univariate model or spatiotemporal mass-univariate model lme_mass_fit_vw or lme_mass_fit_EMinit? 6. After that I don’t understand the subsequent steps. Can you help me understand? Any help is appreciated. Thanks! Swati
