Hi all, This issue was posted by someone else in October (please see below). I have the EXACT same problem. Does anyone have any ideas how fix this? Thanks, Nasim =================================================== Hi, everyone. The tksurfer can't initial a window in iOS 10.7.5. Has anyone met this before?

Measures on Overall Registration Quality in Freesurfer
by Xinian Zuo 17 Nov '12

17 Nov '12

Dear FS Developers, Is there any metrics output by Freesurfer for measuring the overall quality or error of the surface registration from an individual brain to the fsaverage brain? I mean something like the bbregister.dof6.dat.mincost given by bbregister. Many thanks! -- Xi-Nian Zuo, Ph.D of Applied Mathematics (http://lfcd.psych.ac.cn) Google Scholar Citations: http://scholar.google.com/citations?user=a3-gVGMAAAAJ&hl=en

Freesurfer v5.2
by Sourena Soheili-Nezhad 17 Nov '12

17 Nov '12

Hello Freesurfer Development Team, I am in a dilemma to either postpone starting of a work (~400 subjects) till next FS release or not. What do you advise, and does there exist an approximate ETA for v5.2? Thanks in advance, Sourena Soheili-N.

contrast matrix
by xiangbo_2010 17 Nov '12

17 Nov '12

Hi Freesurfer experts, I'm very sorry to bother you, but I am very confused with the following questions: My experimental design includes three discrete factors: factor 1 with three levels (A,B,C ); factor 2 with three levels (O,P,Q); gender (F, M), and one covariate. So I can get 18 classes: FAO, FAP,FAQ,FBO,FBP,FBQ,FCO,FCP,FCQ,MAO, MAP,MAQ,MBO,MBP,MBQ,MCO,MCP,MCQ. I want to perform the interaction between factor 1 and factor 2 regressing out the effect of gender and one covariate, but I don't know the rules for setting the contrasts for the F-test. The contrast matrix I used is: 1 1 1 -1 -1 -1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 -1 0 1 -1 0 1 -1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 1 1 0 0 0 -1 -1 -1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 0 -1 1 0 -1 1 0 -1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 1 1 -1 -1 -1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 -1 0 1 -1 0 1 -1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 1 1 0 0 0 -1 -1 -1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 0 -1 1 0 -1 1 0 -1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 is it correct? Any help will be very appreciated. Best wishes, Bo Xiang

re white matter mask
by Catherine Bois 16 Nov '12

16 Nov '12

Hi, I have a question re the screenshot attached in the present email... Several slices of the white matter mask of this scan seem to have several " holes" ie black spots like this. These parts are included in the brain mask, but the brain mask seems to be quite non-uniform in terms of "whiteness" of the brain mask. I have gone in and filled some in manually; ie done white matter edits, is this the correct way to fix this problem, or do the holes indicate some other problem? Thank you very much for your help, Regards Cathy

reconall without graphics card or GPU?
by Linda Zhang 16 Nov '12

16 Nov '12

Dear all, At our university, we have the option of using a high performance computing facility to run "computing intensive" analysis, but it doesn't have a 3D graphics card or GPU. Is it advisable to run reconall at the facility and visualise the results later on another computer? Running it on my current computer is just taking too much time. Cheers, Linda

Using Subcortical initial output, with "fixed" cortical output
by Mark Fletcher 15 Nov '12

15 Nov '12

Dear FreeSurfers, I am using a Linux computer with FS 5.1 Due to the known "feauture" in version 5.1 where "Control points may adversely affect aseg" but also may alter the " subcortical segmentation", is it acceptable to use the initial subcortical output (before adding control points) for analysis, and then use the cortical volumetric output (after control points have been added) from corrected brains? If this is acceptable, any suggestions on how to phrase this for a paper without it seeming like FreeSurfer has a bug? Sincerely, Mark
