Because of the vertex correspondance, you can actually just append the
scalars to the native space surfaces. Given the available tools, the
easiest way to achieve this is to transform the vertex-analysis surface
back to native space.
for firstflirt_xfm in *_t1_to_mni.mat ; do
f=`basename firstflirt_xfm .mat`
run_mesh_utils -m vertex_analysis_results.vtk --inverse -t
$first_flirt_xfm -o ${f}_to_native.vtk
done
Where its loop around the transforms to mni space output by first_flirt.
If interest there are also ways to output the 'aligned' surfaces that are
used in the veretx analysis, so that you can visualize the vertex
variation.
