you can see Beckman 2003, NI 20, p12052 and Thirion, 2007, NI 35, pg 105.

I've attached the source as well. The method that is actually implemented is equation 5 in Thirion.

Hi,

I have a question about the "weighted random effects" option in the "mri_glmfit" command. Are there any specific references (papers or books etc.) for that approach, i.e., using contrast variance images to weigh the contrast images in a second-level analysis. Also, would it be possible for me to access the source code of that particular module ("mri_glmfit") to see how the algorithm is implemented? The FreeSurfer source that used to be accessible from the ftp server (surfer.nmr.mgh.harvard.edu) is not only there for some reason.

Thank you very much!
