Hi all, I am trying to extract vertexwise surface area values in an ascii files. For that I am doing
mri_surf2surf --hemi ?h --srcsubject <subject dir> area --src_type curv --trgsubject fsaverage --trgsurfval XYZ-area --trg_type curv mris_convert -c XYZ-area ?h.white XYZ-area.asc However I am getting surface area values for some vertices as negative. 1) Am I following correct steps while writing vertex-wise values in ascii files? 2) Aren't values of surface-area supposed to be non-negative? I am not sure what I am missing here. Thanks for the help. -Sabin
