# Perform Fermi surfaces calculations using PKKprime code
The computation of Fermi surfaces, or band structures can be easily done
setting the *RUNOPTION**qdos* (see [Qdos tutorial](jumu/qdos"wikilink")). The "qdos approach" is based on the scan of the k-space for a given energy (or different energy values if we are interested on band-structure calculations) by the spectral function
