[Wien] Regarding bandstructure calculation in WIEN2k 17.1

It depends on what Linux distribution you are using.

For example, if you are using Ubuntu, evince should be the default 
PostScript viewer [ https://help.ubuntu.com/community/Evince ].  If not 
installed, you should be able to install it with:

sudo apt-get install evince

If you are using Fedora [ 
https://ask.fedoraproject.org/en/question/43700/where-can-i-download-the-latest-version-of-evince-pdf-document-viewer-rpm-from/ 
]:

yum install evince

If you prefer a different PostScript viewer, you would have to use a 
search engine to look up how to install it for your Linux distribution.  
In Ubuntu, you can also use the search box in the Ubuntu Software Center 
[ https://en.wikipedia.org/wiki/Ubuntu_Software_Center ] to find other 
PostScript viewers.  For other Linux distributions, you would have to 
check your operating system documentation to see what GUI package 
manager is available.

If the plot (jpg) is not displaying in w2web, you may have to install 
ghostscript, for example [

yum install ghostscript
