Hello FreeSurfer Developers,

I'm attempting to compute cortical thickness and to analyze it between groups.
So I perform "recon-all", but rather than using recon-all -all, some problems arise while performing each of the steps in it. These problems are as follwing.

sample-001.mgz and sample-002.mgz in /usr/local/freesurfer/subjects/ are used. What is this problem happening?
