Dear all,
I am trying to compute the local gyrification index but unfortunately encounter the problem below. Matlab Version (7.7.0.471 - R2008b) and also the Image Processing Toolbox are installed on my computer.
As I understand 'make_outer_surface' does not find 'tmp-mris_compute_lgi-lh.pial/lh.pial.filled.mgz.gz'. However when checking the surf directory I can see that tmp-mris_compute_lgi-lh.pial/lh.pial.filled.mgz.gz exists. So maybe it is just a path problem?
Any help is greatly appreciated!
Best wishes, Christian Scheel
