External Email - Use Caution        

Dear Freesurfer experts, 

I am trying to install Matlab version 2012b but a message appears: command not found. 

Firstly, I ran: sudo cd $FREESURFER_HOME/bin && curl MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be https://raw.githubusercontent.com/freesurfer/freesurfer/dev/scripts/fs_install_mcr -o fs_install_mcr && chmod +x 
Then I typed: fs_install_mcr R2012b and I receive: command not found. 
My FS version is 6 and I have already install Matlab2016_b on my Mac. 

Could you please help me resolve this issue? 
Thank you in advance,
Georgia
