Hi,
I am examining the affect a metal artifact has on fMRI data, and I am using Eccentricity mapping with the retinotopy analysis in FSFast. I was recently asked to switch from examining the difference in the fsig to examining the difference in the betas. I opened up beta.nii.gz and I can see that it has a size of:
1 #of vertices 1 39
Can you explain to me, how I figure out where each of the 39 come from (and possibly point me to which of these might be appropriate to use?)?
Thank You, Dan
