 +===== Duplicating WIEN2k Sessions =====
 +It is sometimes useful to duplicate a previous calculation (e.g. to vary parameters in DOS or optical calculations without having to repeat SCF).  This can be done fairly easily with a few commands.  You'll need to connect to the server using ssh.
 +  - Duplicate the existing calculation.  In your main Wien2k directory, run <code>cp -R old_case new_case</code>
 +  - Go to the new case folder. <code>cd new_case</code>
 +  - Batch rename old_case.* files <code>rename -v 's/old_case/new_case/' old_case*</code>
 +  - Log in to the w2web interface and create a session called new_case in the new_case directory you previously created.
