[Freesurfer] Freesurfer v5.2

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. ___ Freesu

[Freesurfer] Measures on Overall Registration Quality in Freesurfer

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 App

If you look in the recon-all.log it should give the final error functional value from mris_register cheers Bruce On Sun, 18 Nov 2012, Xinian Zuo wrote: > Dear FS Developers, Is there any metrics output by Freesurfer for > measuring the overall quality or error of the surface registration > fr

[Freesurfer] contrast matrix

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:

Re: [Freesurfer] contrast matrix

Hi Bo, I'm definitely not an expert of this, but I see that you really nead some help, so I tried to look at your matrix. From my humble opinion it doesn't look correct. Firstly, the first 9 groups are male groups and the last 9 are female groups. Then why are all female groups assigned 0 in the m

Re: [Freesurfer] contrast matrix

Dear Cherry I our analysis, the gender as a Covariate, so all female groups assigned 0 in the matrix, following is new matrix: 1 -1 -1 -1 -1 -1 0 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 1-1 -1 0 -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 0 0 0
