Still somehow I haven't manage to make it work when I ran the suggested

Any advise?

Hi Doug,
I found a workaround. I used matlab code from from gradient_nonlin_unwarp to
remove the c_ras offset from the vertex coordinates and set c_ras to 0. Then I
mris_convert the new surface to .gii. This gives me perfectly aligned surfaces.
Thanks for your help,

sheet the same as LGI?
thanks so much,

Hi Alan,
lGI is different from the folding index. lGI is not yet extracted automatically
in the different regions, because it's more meant to be use at the vertexwise
level. But you can easily obtain the lGI values averaged over the Desikan's ROI
using the following command:
Not necessarily.
