I am a bit stuck and was hoping for some advice!

I am using Matlab Student version for my research and was trying to determine local gyrification index on some samples that I have processed via the recon-all -all step.

When I run recon-all -lgi on my subject, it starts up, is able to access MATLAB, but then gives an error >> Undefined function or variable 'make_outer_surface'. Am I missing a package from the MATLAB student version? How do I solve this? Any help will be greatly appreciated!!!
