However, I'd like to recover the cortical parcellation for the downsampled surface.
I tried to decimate the pial & white surfaces, generate a corresponding thickness file and then
mris_sample_parc -ct /opt/freesurfer/FreeSurferColorLUT.txt tvb lh aparc+aseg.mgz decim.annot
but this seems not to generate a proper annot file. The same procedure works for the original pial & white surfaces.
The alternative, it appears to me, would be to generate decimated white, smoothwm, inflated, sphere, curv & sulc surfaces, apply mris_register to obtain decimated sphere.reg and then mris_ca_label to obtain a proper annot file for the decimation.
I will try this, but any insight would be appreciated.
