hi Bruce,
what if I have .feat files from FSL which have already been processed for functional analysis......how can i use transformation tools for going from 4D time series-functional to FS average template surface space for FSL output?.....

Hi KK,
mri_vol2surf will take it to individual subject space, then mri_surf2surf can be used to bring it into average space if you want.
cheers Bruce

Hi Everyone,
I am new to FreeSurfer, and having some issues with what I believe should be a pretty basic operation.
My goal is to register a 4D functional time series to FS average space
for further connectivity analysis in Matlab (similar to the recent Yeo et al. J Neurophysiology paper). We have run recon-all without problems on the structural data, but I am having trouble getting the whole functional time series into surface space. When I perform FS-FAST just from pre processing till automatic registration of func-struc, "register.dof6.dat" is produced, which includes input registration matrix. Is their any way to apply this registration matrix to the 4D time series directly, so that the output is in FS average template surface (rather than volumetric) space?
Many thanks, kk
