Hello, 

I have a few questions that I hope can be answered:

Q1:

How can '.label' files be turned into the necessary '.gca' file needed for the recon-all pipeline. Starting for the first step in auto-recon2.

What else other than the '.label' files  would be needed to create this '.gca' file?

Q2: 

How to get the seg_edited.mgz file? I would want to use this file in the rebuild_gca_atas.csh script.

Q3:

Can the rebuild_gca_atlas.csh script be used to make a replacement for the RB_all_2008-03-26.gca file from the average folder?

Q4:

Is there a way to avoid needing the .gca file if cortical thickness measurements is the only goal?

Or could there be a limited number of labels needed incorporated into the .gca file for this goal. Ex. Just Cerebral cortex ROI's.

Thank you for any help,
