Did not find dscalar.nii file of vertex area

Dear community:
	When using ciftify_recon_all to convert freesurfer's results to HCP format, I found the dscalar.nii file of thickness, but did not find the dscalar.nii file of vertex area, and wants to ask the specific location of the dscalar.nii file of vertex area. If I this file was not generate , how do I generate it myself?
