The error would indicate that the number of elements in 'lh.area' and 'lh.area.pial' are not the same. You can check this also with mris_calc:

mris_calc lh.area stats

mris_calc lh.area.pial stats

which will provide some basic statistical output, including the size (i.e. number of elements) of each. The sizes have to match in order to add.

Hi list,

I have a problem during recon-all

#@# Surf Volume lh Thu Sep 12 08:25:31 CEST 2013 /Applications/freesurfer/subjects/subject_prova/Con28/SUBJECTS_DIR/surf \n mris_calc -o lh.area.mid lh.area add lh.area.pial \n

mris_calc: Sorry, but I seem to have encountered an error. While checking on input filetype sizes, I found a size mismatch, i.e. len(input1)!=len(input2)
