[Freesurfer] DODS/DOSS

2013-10-10 Thread Iris Frankenberg
Hi mailinglist, I have a question regarding DOSS/DODS. In the mailinglist I read that if you do a group analysis, you have to check for interaction between your continuous variable and categorical variable in DODS, and if there's no interaction, you can use DOSS. This however leaves a few qu

Dear Experts, Hi, I have already done my data analysis having group as fixed factor and age as nuisance factor in QDEC FS 5.3. I also need to run it with DOSS. Would you please advise how to run the same analysis with DOSS from terminal and if it is possible to look at the results in QDEC Display a

Just wondering if anyone has attempted to process T1-mpr data for a 1yr-old subject or if this is possible with FS. Our data is of reasonable spatial resolution (1mm isotropic), however the flip in gm/wm intensities is still occurring at this age. I presume these data would also be problematic d

Hi Jim, Using the current FS recon pipeline with your data is indeed not feasible. We are in the process of creating another pipeline geared towards that age range. Lilla On Thu, 10 Oct 2013, Alexopoulos, Dimitrios wrote: > Just wondering if anyone has attempted to process T1-mpr data for a

[Freesurfer] QDEC issues

2013-10-10 Thread Gautam, Prapti
Dear FreeSurfers, While running analyses in QDEC, it only allows me to select one continuous variable at a time instead of the usual two –so running analyses in QDEC is extremely limited. I have used QDEC before, and this is a new issue. Has anyone else encountered this problem? Thanks, Prapt

Hi Liv, What you are asking for is quite ambitious. As you have noticed, most of the image processing tools fail on the infant data sets as they are usually of much lower SNR, they have changing GM/WM contarst, higher noise and a much smaller anatomy. So it is not only a question of creating

[Freesurfer] Gender as a nuisance factor

Dear Freesurfer experts, I'm performing a group analysis in Qdec correlating a biological marker and the CTh, and I would like to covariate the gender and age effect, i.e. ideally get rid of both effects and isolate the biological marker effect. So, I understand that the age effect is (at least

Hi Emily - You can't download tracula separately from the rest of freesurfer, you'll have to download freesurfer 5.3. It works on any platform that the rest of freesurfer works. The one thing that tracula uses from the freesurfer recon is the aparc+aseg.mgz. I have never tried running tracula
