Hello all, I have started with a group analysis using qdec and have some questions:
1. loading fsaverage into tkmedit along with rh.white and lh.white surprised me that the pial surfaces do not run under the skull, as I see it on a single subject but copy the white matter. It is also correct, but it looks a bit odd. I suppose that this is a result of averaged out WM, but my concern is whether it can anyhow affect the analysis 2. I am interested in group analysis of LGI. I do not see however ?h.pial_lgi in fsaverage. Also when I run qdec, lgi is not among the parameters available for testing. I could backup say the thickness files and than rename my lgi results as thickness, but if there is a more straightforward solution I would like to avoid this trouble 3. Since lgi is for each vertex calculated over a certain diameter, thus has inherent smoothing. Therefore I would tend to use 0 smoothing in GLM. What do you think about this idea?
