Im not sure if its the problem or not, but seems that its the file permission error.
Either do "sudo su" and re-run your command as root or change the file permissions in /subjects folder.
Running commands as "root" is generally not recommended.

Hello freesurfer developers,
I installed FreeSurfer on my computer today using the instructions found here: https://surfer.nmr.mgh.harvard.edu/fswiki/DownloadAndInstall. After installation, I proceed to the “test your FreeSurfer Installation” section. Upon trying the first test, I ran the following and code and received the following error.

I’ve searched the list and was unable to find someone with the same error in the archives. Any thoughts on how to fix this?
