Gray matter
by Jordi Delgado 22 Mar '13

22 Mar '13

Dear FS experts, I have a double question about the gray matter calculations in FS: - Revising the aseg.stats, I noticed that there is a Total Gray Volume calculation. Is there a mgz volume with the gray matter? I cannot find it on the output mri folder... - How this total Gray Volume is calculated? Which structures are taken into account? Is there any file with this information Kind Regards, -- Jordi

Re: [Freesurfer] subcortseg error - ?h.white surfaces not available

Still having issues with the subcortseg flag in v5.2.0 ... Trying to take a look at the source code, I did checkout from the cvs but it failed due to the following error: cvs [checkout aborted]: Could not map memory to RCS archive /usr/fscvsroot/dev/distribution/average/cvs_avg35.tar.gz,v: Cannot allocate memory Any problems with the cvs server? Your help will be very much appreciated.

vox2ras and vox2ras-tkr
by Eric Larson 21 Mar '13

21 Mar '13

Does anyone have code available for reading the vox2ras-tkr transform from .mgz files? I am working on implementing the transform outlined on the Freesurfer wiki: MNI305RAS = TalXFM*Norig*inv(Torig)*[tkrR tkrA tkrS 1]' TalXFM: subject/orig/transforms/talairach.xfm Norig: mri_info --vox2ras orig.mgz Torig: mri_info --vox2ras-tkr orig.mgz I can get vox2ras-tkr (a.k.a., Torig) using mri_info, but it would be better if they were available in the python package nibabel for use in mne-python (for easy conversion from surface to MNI coordinates). nibabel already supports reading the --vox2ras transform, but I need to code the other one in order to avoid a dependecy in our code. Does anyone have code to extract that information? MATLAB, Python, C code, or heck, even pseudocode would help. If not, if anyone has helpful information on the specs on the .mgz specification, maybe it won't be too difficult to code from scratch... Eric

Hi Stefano - There's nothing in these screenshots that tells you that the eigenvectors are correct. These are vectors, so the way to check them is to display them as lines. You display dtifit_V1 as lines, overlaid on dtifit_FA. Then you see if the lines point in the right direction. a.y On Fri, 22 Mar 2013, stdp82(a)virgilio.it wrote: > Here they are attacked. > Thanks, > > > Stefano > > > > > ----Messaggio originale---- > Da: ayendiki(a)nmr.mgh.harvard.edu > Data: 21-mar-2013 21.50 > A: <stdp82(a)virgilio.it> > Cc: <freesurfer(a)nmr.mgh.harvard.edu> > Ogg: Re: R: Re: [Freesurfer] R: R: Re: Problem with tracula: incomplete or > lacking tracts > > > Can you send a screenshot that shows dtifit_V1 and dtifit_FA? > > On Thu, 21 Mar 2013, stdp82(a)virgilio.it wrote: > > > I have checked the gradient directions.

help with contrasts
by Laura M. Tully 21 Mar '13

21 Mar '13

hi Experts, I'm struggling to conceptualize the appropriate contrasts for my cortical thickness analysis. I have four classes [two groups; two levels (patients,controls; male,female) and two behavioral variables. I want to see if together the two variables account significant proportion of the variance in y (thickness) and if this differs by group whilst regressing out gender. - i.e. if I enter both behavioral variables into the model does it account for more variance than either variable on their own (after controlling for gender)? What I have is this: .5 .5 -.5 -.5 0 0 0 0 0 0 0 0 .5 .5 -.5 -.5 Does this look right? Thanks! Laura. -- -- Laura M.

I have checked the gradient directions. How can I resolve the brain mask problem. Can I send you my files of this subject? Stefano ----Messaggio originale---- Da: ayendiki(a)nmr.mgh.harvard.edu Data: 20-mar-2013 22.46 A: <stdp82(a)virgilio.it> Cc: <freesurfer(a)nmr.mgh.harvard.edu> Ogg: Re: [Freesurfer] R: R: Re: Problem with tracula: incomplete or lacking tracts There are chunks of the brain missing from the brain mask. This may cause some tracts to be incomplete or missing. But you should still check that the gradient directions are correct, so you know if you have multiple problems or just one. The FA map can't tell you if the gradient table was correct, you have to check the eigenvectors in dtifit_V1 for that.

v5.2.0 preproc-sess failing on 3dvolreg.afni
by Y.V. Jiang 21 Mar '13

Hi Doug, I was running preproc-sess in the newly released freesurfer-5.2.0. The command I used was: preproc-sess -sf sessid -df sessdir -fsd bold -surface fsaverage lhr -mni305 -fwhm 6 -per-run The program failed with the following errors: 3dvolreg.afni -verbose -dfile 004/fmcpr.mcdat -1Dmatrix_save 004/fmcpr.mat -base 004/tmp.mc-afni2.29239/tempvol.nii.gz -prefix 004/tmp.mc-afni2.29239/outvol.nii.gz 004/tmp.mc-afni2.29239/invol.nii.gz 3dvolreg.afni: symbol lookup error: 3dvolreg.afni: undefined symbol: afni_ncerr ERROR: 3dvolreg.afni Invalid null command. I have the file 3dvolreg.afni in $FREESURFER_HOME/bin. There is another file of the same name under afni/bin. Preproc-sess is relying on the version in $FREESURFER_HOME/bin. Do you know what the problem is? Should I replace freesurfer's copy of 3dvolreg.afni with AFNI's copy of 3dvolreg.afni? Thanks. -Yuhong

y values from glmfit-sim
by Laura M. Tully 21 Mar '13

21 Mar '13

Hello experts, could someone clarify for me what the y values in the xxx.ocn.y.dat files represent following glmfit-sim? are they the residualized y values of avg cortical thickness in that specific cluster after regressing out the effect of any predictor variables in the glm? Thanks! Laura. -- -- Laura M.
