[Freesurfer] reshape command

Dear Freesurfers,

I am trying to reduce the number of vertices to display with the wireframe overlay on the inflated cortical surface. To this aim, I am using the following command line:

mri_surf2surf --s Estudio_EHM_average --sval-xyz inflated --tval /root/trabajo/freesurfer/subjects/Estudio_EHM_average/surf/lh.reshaped.inflated --tval-xyz --hemi lh --reshape --reshape-factor 7

But when I load the reshaped surface in Matlab it contains the same number of vertices as originally. Why the reshape command (factor 7) is not decreasing the number of vertices on cortical surfaces?

Thanks in advance.
