Dear FS experts
I have done group comparisons wrt thickness, surface area and volume. The found clusters were written out as annotations, transformed into each individual space, and then the corresponding values were extracted.
When using mris_anatomical_stats, values are different for thickness and volume maps depending whether I used the --nsmooth 15 option or not. So good so far.
However, when using the same command (see below) for ?h.area files, extracted values are the same whether or not I used the --nsmooth 15 option.
mris_anatomical_stats -a rh_area_parietal_insular.annot -t rh.area -nsmooth 15 -f subject/stats/output.stats subject rh
It seems that the --nsmooth 15 option in mris_anatomical_stats does not affect (smooth) the area maps that were used to extract the values.
Is this what one has to be expected? Or is it something like a bug?
Thanks in advance Best regards Jürgen Hänggi
