Matt, Thank you very much for your prompt response.
Is it also possible to find outliers and replace them with the local average as, caret does for myelin mapping? Also I'm not familiar with the workbench software, could this diffusion data func.gii be transformed to the MNI fs average surface, using the workbench? And one last question, is that the MATLAB gifti toolbox doesn't seem to take care of func.gii,files and it only imports the vertices and faces. How could the assigned values also be imported to the MATLAB? Sorry for the long list of questions Cheers Arash > On Oct 24, 2013, at 9:01 PM, "Glasser, Matthew" <[email protected]> > wrote: > > Yes use the native surface files in ${StudyFolder}/${Subject}/T1w/Native for > mapping diffusion data to the surface.
