Hi Ed,
the FSL results (COPEs) for each subject/run are converted onto the
spherical surface (this is more-or-less equivalent to talairach surface
space) using a freesurfer program called mri_vol2surf. mri_vol2surf can
produce analyze output files which will look like volumes but are just a
convenient way to save data. Then gfeat can be run on these data sets.
The results are then converted back into surface format using
mri_surf2surf which can then be rendered on the surface using tksurfer.
The full description is given in the web site that Steve pointed to.

Note: you can get help for mri_vol2surf and mri_surf2surf by running
them with the --help option. You'll also need a program called
tkregister2 (replaces fslmat2register) to convert the FSL registration
matrix to something freesurfer understands (again, see --help).
