Thanks, Kevin So, I guess there is nothing special about retinotopy data, but the functionl overlay that I got doesn't look right. (not much activation)
Here is the two steps that I've done for the functional data before I overlay it onto anatomical data. Any comments are appreciated. 1. use "mricro" to turn functional data into Analyze format (*.img and *.hdr). 2. use "mri_convert" to turn the Analyze format data into *.bfloat to use them in functional overlay. I guess that something is missing. That is I did not include anything about the experimental design, e.g., 1 2 1 2 1 2, or 1 2 3 4 1 2 3 4, etc. Where do I include such information in the analysis? I know where I put the design info in FSL, but not here in Freesurfer?
