I'm having an issue while attempting to download Matlab 2012 runtime for its use in the hippocampal subfield segmentation. The error is: "Warning: Failed to create the file runtime.tar.gz: Permission denied". 

See details below: 

 curl "https://surfer.nmr.mgh.harvard.edu/fswiki/MatlabRuntime?action=AttachFile&do=get&target=runtime2014bMAC.tar.gz" -o "runtime.tar.gz"

curl: (23) Failed writing body (0 != 7771)

Any ideas why this is happening? 

Thank you,
