FS volume estimates
by Otília 08 Jun '16

08 Jun '16

Greetings, I have two questions regarding FS volume measurements. I intend to use the volume information of .stats files but I got some doubts regarding the methods used. 1) I read that eTIV estimation is based on the TAL transformation, but what about the volumes of cortical and subcortical areas? Is it a simple voxel count? 2) In some studies the authors normalize the volumes to eTIV. In others the authors don't do any normalization. Some of them use it as co-variate. What's your opinion regarding this matter? Thank you in advance! Best regards,

Hi there, Looking over the freeview development page, it looks like there are some (relatively) new features that would come in handy. Could I get a link to download the latest freeview beta?

cespct in FS 5.3
by S.V.Shepherd [work] 08 Jun '16

08 Jun '16

Hi all, I ran an analysis on data after dividing each voxel mean across the run, and then multiplying by 100. (My intuition was that the percent signal change should be more consistent across varying SNR that the non-normalized betas). I had naively expected ces.nii and cespct.nii to be equivalent in this case, but in fact, cespct.nii is steeply larger and only imperfectly correlated with ces.nii. What am I missing? stephen *stephen v. shepherd phd* The Rockefeller University / 1230 York Avenue / New York NY 10065-6307 USA // 212.327.7699

aseg.stats and aparc.stats reliability
by Greenberg, Jonathan 08 Jun '16

08 Jun '16

Hello Are the volume and thickness measures in FreeSurfer's aseg.stats and aparc.stats accurate and reliable enough to assess changes in volume and thickness longitudinally? I have heard there have been some accuracy/reliability issues in these files in older versions of FreeSurfer. Is the data in these files strong enough to base a publication on? Thanks! Jonathan

CM_Group_analysis_Create tha contrast and design matrix by myself
by Hao wen 08 Jun '16

08 Jun '16

Hello, freesurfers: I am doing group analysis, with two diff groups, so I want to know that how to create my own Contrast and Design matrix, because that I know in QDEC and CMline, in the freesurfer wiki, You just give the example for the DODS & DOSS, but it is not so flexible! I know that we should define --X in the command mris_glmfit, but I got some problems, here is my work flow: #set the SUBJECTS_DIR export SUBJECTS_DIR=/aramis/dataARAMIS/users/junhao.wen/Data_AD_CN/ADNI_60_AD_CN_object_recon_all_output/ cd $SUBJECTS_DIR/glm/AD_CN_COVARIATES_AGE_GENDER/OWNDESIGNED_Alex_covariates_design_matrix_surfstat_version mris_preproc --fsgd AD_CN_COVARIATES_AGE_GENDER.fsgd \ --cache-in thickness.fwhm15.fsaverage \ --target fsaverage \ --hemi lh \ --out lh.AD_CN_COVARIATES_AGE_GENDER_thickness_15.mgh mri_glmfit \ --glmdir lh.AD_CN_COVARIAETS_AGE_GENDER.glmdir --y lh.AD_CN_COVARIATES_AGE_GENDER_thickness_15.mgh \ --C AD_CN_COVARIATS_AGE_GENDER.mtx \ or --C contrast.mat --X X.mat --surf fsaverage lh \ --cortex \ so, after I run the mri_glmfit, i got the errors, like, you should define the --X or without --C, or cant find command --surf, --cortex, i dont really understand what is the problem, and I create the design matrix and contrast matrix in Matlab Actually, I run the DODS, it works well, and the workflow, I dont change for the command mris_preproc, I just change the flags in mri_glmfit, someone could help me for this? Thanks in advance! Hao

Re: [Freesurfer] ERROR: cannot unpack mosiacs without ASCII header
by Aloi, Joseph 07 Jun '16

Hi Doug, I do not believe the files have changed in any way since I started using them; I uploaded some dicoms for you to look at and the recon-all log to the file drop a few minutes ago (with more details). Thank you for all your help! Joseph Aloi Graduate Student, MD/PhD Scholars Program Department of Pharmacology and Experimental Neuroscience University of Nebraska Medical Center Neurobehavioral Research Assistant, Center For Neurobehavioral Research Boys Town National Research Hospital Have the dicom files changed in any way? In the failure, the problem maybe that it thinks that the series is truncated (the header thing is not a problem). Do you still have perms to all the files in that folder? I noticed in the analysis that succeeded had a bunch of these statements (never seen it before): Agreeing to the Xcode/iOS license requires admin privileges, please re-run as root via sudo. Feel free to tar up the dicom folder and send it to me at our file drop.

errors in wm and pial boundaries
by Corinna Bauer 07 Jun '16

07 Jun '16

Hello all, We are analyzing data from our collaborators and are running into some difficulties with the accuracy of the pial and wm boundaries. The wm.mgz appears to follow the actual WM, independent of the wm surface boundary. Attached is an example showing two types of problems. 1. the WM surface is inaccurate regardless of the number of control points used. 2. The pial surface is inaccurate, missing a bunch of the sulcal and gyral patterns of the left parietal lobe (see area around cursor). For completeness, I have also included the wm.mgz at the same slice. I should mention that these problems has been occurring in multiple subjects. Any suggestions?? Thanks Corinna
