I get the following error:

I ran the command in debugging mode and x and yi are both empty variables.

I am using a freshly installed version of the Lion OS X 10.7 (64b Intel) version of FreeSurfer (freesurfer-Darwin-lion-stable-pub-v5.3.0.dmg; freesurfer-Darwin-lion-stable-pub-v5.3.0) and am running on OS 10.11.6 using MATLAB version R2015b (8.6.0.267246). The recon-all.log is attached.

Let me know if there is any further information I can provide and thanks for producing such a fantastic piece of freeware.
