Experts

I am stuck up with a real basic issue, which I have done easily manytimes in the older version. I have downloaded and installed the stable v4.4.0 version . I am trying to create a new subject directory, but its throwing the error

 cd subjects
barnali-work:/usr/local/freesurfer/subjects> mksubjdirs ja
mkdir: cannot create directory `ja': Permission denied
ERROR: creating directory ja


I tried doing chmod 755 from root, it says operation not possible.


Where  am I going wrong

Thanks
