| * To look at your structure in **real space**, go to the ''File'' menu, ''Open WIEN2k Struct file''. You'll get a list of your directories in Wien, and you select the one you're interested in, say ''TiC'', then click ''OK''. You'll get a list of the files in the ''TiC'' directory. Select the one called ''TiC.struct''. Click OK. You'll be able to rotate the structure expand it and so on using the graphical interface. | * To look at your structure in **real space**, go to the ''File'' menu, ''Open WIEN2k Struct file''.
