bad midline cut
by Gabor Perlaki 23 Sep '17

23 Sep '17

I've a subject, where the midline cut is bad (see the attached pictures), therefore the segmented left lateral ventricle also includes considerable number of voxels from the right one. Is it possible to correct it somehow?

Error in segmentHA_T1
by Tiril Pedersen Gurholt 22 Sep '17

22 Sep '17

Dear Experts, I recently installed Freesurfer development version (dated Sept. 16, 2017) on a Mac Sierra (10.12.6). When trying to run segmentHA_T1.sh I encounter a java problem: "JavaVM: Failed to load JVM: /Library/Java/JavaVirtualMachines/jdk1.8.0_144.jdk/Contents/Home/bundle/Libraries/libserver.dylib». See full error message below. The java.opts file in MCRv80/bin/maci64 is dated Nov. 5, 2014. There also appears to be a problem with a Matlab app (?), although matlab runtime has been installed. Any ideas as to how to fix these problems?

curvature
by Jacobs H (NP) 22 Sep '17

22 Sep '17

Dear FreeSurfer, In the stats files (e.g aparc) there are also statistics for the "integrated rectified mean curvature", "integrated rectified gaussian curvature", "folding index" and "intrinsic curvature index". To what kind of properties do these measures refer and which one is advised to be used? Many thanks! Heidi

Adjusted or unadjusted CT values and interpretation of volume values in ocn.dat from group analysis
by Elizabeth Bartlett 21 Sep '17

21 Sep '17

Hello Freesurfer experts, I have performed a group level analysis of volume and cortical thickness using mri_glmfit and performed multiple comparisons correction with mri_glmfit-sim. I used the contrast matrix 0 1 0 to analyze 1 group with 2 covariates, along the 1st covariate (education) with the 2nd covariate being age. I get 2 significant clusters (after mult. comp. corr.) for CT and 2 for volume. When I look at the values in ./cache.th30.abs.y.ocn.dat, the average CT values within my sample are 2.57 and 2.50 for the 2 regions. *My first question is: *are the CT values outputted to ocn.dat adjusted for my 2nd covariate (age) or are they unadjusted CT values within the sig. cluster? The volume values contained within the ocn.dat files are also in the same range as the CT values, with averages of 2.50 and 1.87 for left superior frontal and right inferior parietal volume, respectively. *My second question is:* What is the metric for volume reported in ocn.dat? These values seem too low to be total cluster volume for each subject expressed as mm^2. The volumes reported in ./cache.th30.abs.sig.cluster.summary are more like what we I expect for volume (283.24 mm^2). Could these values be the average volume surrounding each vertex in the inflated mesh (volume contained within the surrounding vertices)? Thank you, Elizabeth

merge in a sigle label the results obetained in fs-fast
by stdp82＠virgilio.it 21 Sep '17

21 Sep '17

Hi list, I would to merge (separatelly pos and neg) in a sigle .label which contain all the clusters which represent the seed-cortical connectivity after fs-fast analysis.I aim to avoid to extraxt manually single label for cluster by tksurfer. Thanks, Stefano
