yes, it divides along the main eigenaxis, that is what it is intended to do.

I have used mris_divide_parcellation in the pericalcarine and it divided
perpendicular to the main eigendirection and not parallel as I suppose it
would do. (picture attached)

Is that correct?

thanks

Right?

 I think it will do it in the other direction, but the code could be
modified to divide along the smaller eigendirection. Or you could draw it in
fsaverage and just map the labels to your subjects. Calcarine aligns so well
that this method would probably be fine

I have a fMRI study where I need to quantify activation in the
pericalcarine_LH and pericalcarine_RH.

The problem I'd like to solve is to subdivide  pericalcarine_LH and
pericalcarine_RH in its superior and inferior parts. Is there any
automatic way to make this subdivision?

thanks
