Note: ESPRESSO examples are compatible with Quantum ESPRESSO 5.0 and later versions.
If you want to run them with Quantum ESPRESSO 4.3.2 or earlier version, you should modify the input files for pw.x.
Change "calculation = 'bands'" to "calculation = 'nscf'" and "CELL_PARAMETERS" to "CELL_PARAMETERS cubic".

This directory contains example runs for a variety of physical systems:
silicon: a bulk semiconductor (includes PREBUILT and reference results; only example for EPM)
sodium: a bulk metal
swcnt_5-5: (5,5) single-walled carbon nanotube, a metallic 1D system
swcnt_8-0: (8,0) single-walled carbon nanotube, a semiconducting 1D system
CO: a small molecule
benzene: a slightly larger molecule (includes G-sphere, SIESTA)

Only silicon is available for EPM.
Only benzene has a run with G-sphere utility or SIESTA.
All the DFT examples may be done with either ESPRESSO or PARATEC.
The silicon example additionally has a tarball of DFT inputs from PARATEC in the PREBUILT directory,
and sample output files from the GW/BSE results as a reference.
Each directory's README tells you how to run it and suggests number of processors and walltime for parallel calculations.
Needed pseudopotentials and some useful scripts for them are contained in DFT/pseudos.
The Si2_bs DFT example shows how to use inteqp.x to obtain a GW bandstructure for silicon by interpolation.

There are also examples in the Visual directory for the scripts there, as well as plotxct.
The testsuite runs may also be consulted, although they are not realistic calculations.
