Dear Freesurfers

I’m running freesurfer through the VirtualBox and when trying to run “recon-all -s mybrain -all -i /home/developer/Desktop/brainscan.nii.gz” I got three error messages telling me I couldn’t create the directories in “/usr/local/freesurfer/7.1.0-1/subjects/mybrain”. How do I grant myself permission to create that directory?

I’ve attached a screenshot of the command and errors in case that helps.

Thanks for your help!
