Thanks Doug. I located the fwhm.dat file in my qdec output folder for the analysis I'm interested in. I see only one number (13.990453) in this .dat file, I was expecting three numbers corresponding to x, y, z directions. Do I assume this is isotropic then, that is: 13.990453 x 13.990453 x 13.990453?

look in the glmfit output folder for a file called fwhm.dat

Sorry for the repost of my last post, but I now realize that what I need is the estimated filter width that was actually used in the qdec analysis not the fwhm that I actually specified, i.e. 10 mm

Dear Freesurfers, I am reposting my message in hopes that someone will reply this time around - still grappling with this problem. Thanks.

Dear Freesurfers, I am trying to use 3dclustsim in AFNI to determine the minimum number of voxel in a cluster to reach significance, my understanding is that in the command line the -fwhm s flag refers to the gaussian filter width and NOT the Gaussian Kernel, can anyone point me to how I might be able to obtain this for each hemisphere in freesurfer? I am using my own average brain that I created, but it would help to know how to do this for the fsaverage as well.
Many thanks for your help!
