Hi Yoonho
That warning is usually benign. Does the recon finish ok?
Cheers

Subject: [Freesurfer] MCSRCH error using sample data (001.mgz and 002.mgz)
External Email - Use Caution
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?
