The argument to --sval-area is the surface that you want to get the area from. If you want the area of the white surface, then just put "white" there. Or you can use "--sval lh.area" instead of "--sval-area white". doug

Dear FS expert
I try to smooth surface area files with the following command:
mri_surf2surf --hemi lh --s MOREA_KG002 --sval-area area --fwhm 15 --tval lh.area.15.mgh --cortex
But there is an error:
srcsubject = MOREA_KG002 srcval = (null) srctype = trgsubject = MOREA_KG002 trgval = lh.area.15.mgh trgtype = srcsurfreg = sphere.reg trgsurfreg = sphere.reg srchemi = lh trghemi = lh frame = 0 fwhm-in = 0 fwhm-out = 15 label-src = (null) label-trg = lh.cortex.label OKToRevFaceOrder = 1 Reading source surface reg /Applications/freesurfer/subjects/MOREA_KG002/surf/lh.sphere.reg Loading source data Reading surface file /Applications/freesurfer/subjects/MOREA_KG002/surf/lh.area nquads=9895939, nvertices=399 ERROR: MRISread: file '/Applications/freesurfer/subjects/MOREA_KG002/surf/lh.area' has many more faces than vertices! Probably trying to use a scalar data file as a surface!
How to solve the problem?
Thanks in advance Regards Jürgen
