====== Band Structure Computation ======
Basic band structure computation is accomplished with the Wien 2k code available on the Jansen server.  The basics of using Wien 2k are on the [[http://www.physics.oregonstate.edu/~tate/COURSES/ph575/doku.php?id=wien|PH575 course wiki]].  Other band structure programs, VASP and FLAIR, are available for use after tutoring from Prof. Guenter Schneider and his group.  Experimentalists should be able to compute a basic band structure of a simple material and be knowledgeable about the language used.

===== 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.
