[Freesurfer] I: Re: (no subject)
Sorry. The 2 lines are red and yellow. But probably nothing changes. Sorry again! --- Dom 13/3/11, Angela Cosentino cosentino_ang...@yahoo.it ha scritto: Da: Angela Cosentino cosentino_ang...@yahoo.it Oggetto: Re: [Freesurfer] (no subject) A: Bruce Fischl fis...@nmr.mgh.harvard.edu Cc: freesurfer@nmr.mgh.harvard.edu Data: Domenica 13 marzo 2011, 07:49 In this way, I see the cortical thickness' value near the curvature indication, voxel-by-voxel. It's ok? And, when I write the command line in tkmedit: tkmedit SUBJECT_ID brainmask.mgz -surfs, I see the brainmask image and two colored line, a red one and a green one. The first one is th edge of cortical surface; the other one is the white and grey matter's edge. Between these 2 lines, the software calculates the cortical thickness. Is this ok?Have I understood well?

[Freesurfer] question about the capability of qdec and using non normal distributed subjects
Hi I am beginner in using Freesurfer. What can of statical analyze is Qdec cable of doing? Can I use data that are not normal distributed since my data sample contains subjects with neuronal damage?

[Freesurfer] cortical thickness and significance of colored lines
To see cortical thickness I used File-- Load Curvature (rh.thick), as you have suggested. In this way, I see the cortical thickness' value near the curvature indication, voxel-by-voxel. It's ok? And, when I write the command line in tkmedit: tkmedit SUBJECT_ID brainmask.mgz -surfs, I see the brainmask image and two colored line, a red one and a yellow one. The first one is th edge of cortical surface; the other one is the white and grey matter's edge. Between these 2 lines, the software calculates the cortical thickness.

[Freesurfer] Questions about GLM, Random and Fixed Effects Analysis in FsFast
Hello Freesurfers I would like to run a specialized group GLM analysis on the volume using estimates from the individual subject analysis in Freesurfer as summary statistics. I would like to learn a little more about how this estimation is done before doing so. I have looked at the documentation for mri_glmfit and the following tutorial: http://surfer.nmr.mgh.harvard.edu/fswiki/FsFastTutorial I also have your 1999/2003 manuscripts on Signal Processing and Statistical Analysis for Event-Related fMRI and fMRI Analysis 101 - Univariate Analysis, but I am not sure if the method has been updated since then. * I noticed there is a weight matrix (W) described for mri_glmfit command. How is this derived and used? I can't find more information about it in the documentation/mailing list. * How are the nuisance regressors organized in the B matrix? I assume the conditions are first? What are the following regressors? * Do you have a similar manuscript that describes just how group analysis is implemented in FsFast? Thank you for your time and help!
