I don't think surf2surf knows how to deal with patches. We always flatten the individual subject surfaces. You could make a label from the patch and map that across subjects with label2label, then use label2patch to turn it into a patch, then flatten it

Hey all I'm trying to morph the fsaverage flat patch (?h.cortex.patch.flat) to the freesurfer sample subject, and getting the following error:

mri_surf2surf --srcsubject fsaverage --srcsurfval lh.cortex.patch.flat --trgsubject sample --trgsurfval lh.cortex.patch.sample.flat --hemi lh ERROR: could not determine type of lh.cortex.patch.sample.flat

mris_convert also didn't work: mri_surf2surf --srcsubject fsaverage --srcsurfval lh.cortex.patch.flat --trgsubject sample --trgsurfval lh.cortex.patch.sample.flat --hemi lh ERROR: could not determine type of lh.cortex.patch.sample.flat [thibault:surf] (nmr-stable53-env) mris_convert lh.cortex.patch.flat lh.cortex.patch.flat.asc mrisFindNeighbors: lh.cortex.patch.flat: face[0].v[0] = 0, but face 0 not in vertex 0 face list

I could read it using the python code in pyCortex: https://github.com/gallantlab/pycortex/blob/00cc7dadd16149ac7f6fe38621c95c43... fer.py#L189

And after that save it as a freesurfer surface: https://github.com/gallantlab/pycortex/blob/00cc7dadd16149ac7f6fe38621c95c43... fer.py#L167

But even after that mri_surf2surf couldn't determine the type.

Any ideas? Thanks, Noam
