Hello,
I have fMRI data from a small group of subjects. I did a surface-based MVPA (in matlab) in subjects' individual space, and for each subject I have a vector of, say, p-values (one value for each vertex). I would like to display these results on a template surface. So I would like to know the mapping for each vertex to the template surface (as described in http://ftp.nmr.mgh.harvard.edu/fswiki/SurfaceRegAndTemplates)
I used mris_register to register individual subjects' surfaces to .average.curvature.filled.buckner40.tif. What is the next step? Is there a way to have the mapping from the resulting registered spherical surface to an inflated (template) surface?
Or should I use mris_surf2surf? If I just want to get the mapping for each vertex of my subject to the template, what arguments to the function should I specify? Are there any additional steps required (like, for example, aligning the surface with the template)?
Thank you in advance, Irina
