INPUT FILE DESCRIPTION
Program: cppp.x / CP / Quantum ESPRESSO (version: 7.4)
------------------------------------------------------------------------
=============================================================================
CP Post-Processing code (cppp.x)
=============================================================================
The cppp.x code is an utility that can be used to extract data from the CP
restart and CP trajectory files.
INPUT:
=====
the program read the input parameters from the standard input or from
any other file specified through the usual "-input" command line flag.
The input parameters, in the input file, should be specified in the inputpp
namelist follow:
&INPUTPP
...
cppp_input_parameter
...
/

+--------------------------------------------------------------------
+--------------------------------------------------------------------
Variable: fileout
Type: CHARACTER
Default: 'out'
Description: basename of the cppp.x output files

Variable: output
Type: CHARACTER
Default: 'xsf'
Description: a string describing the output format to be performed,
allowed values: 'xsf', 'xyz'
xsf xcrysden format
xyz XMOL format
+--------------------------------------------------------------------
+--------------------------------------------------------------------
Variable: outdir
Type: CHARACTER
Default: './'
Description: directory containing the CP trajectory files (.evp .pos .cel ...)
and restart files ( .save ) to be processed
+--------------------------------------------------------------------
+--------------------------------------------------------------------
Variable: lcharge
Type: LOGICAL
Default: .false.
Description: OBSOLETE - no longer implemented. Use "pp.x" instead.
+--------------------------------------------------------------------
+--------------------------------------------------------------------
Variable: lforces
Type: LOGICAL
Default: .false.
Description: This logical flag control the processing of forces.
.TRUE. extract forces from trajectory files and write
them to xcrysden file
.FALSE. do not process forces
+--------------------------------------------------------------------
+--------------------------------------------------------------------
Variable: ldynamics
Type: LOGICAL
Default: .true.
Description: This logical flag control the processing of atoms trajectory.
.TRUE. process CP trajectory files and generate a trajectory
file for xcrysden (.axsf)
.FALSE. do not process trajectory
+--------------------------------------------------------------------
+--------------------------------------------------------------------
Variable: lpdb
Type: LOGICAL
Default: .false.
Description: This logical flag control the generation of a pdb file.
.TRUE. generate a pdb file containing positions and cell
of the simulated system
.FALSE. do not generate pdb file
+--------------------------------------------------------------------
+--------------------------------------------------------------------
Variable: lrotation
Type: LOGICAL
Default: .false.
Description: This logical flag control the rotation of the cell
.TRUE. rotate the system cell in space in order to have
the a lattice parameter laying on the x axis,
the b lattice parameter laying on the xy plane
.FALSE. do not rotate cell
+--------------------------------------------------------------------
+--------------------------------------------------------------------
Variables: np1, np2, np3
Type: INTEGER
Default: 1
Description: Number of replicas of atomic positions along cell parameters.
CURRENTLY DISABLED
If np1, np2, np3 are 1 or not specified, cppp.x does not
replicate atomic positions in space.
If np1, np2, np3 are > 1 cppp.x replicates the atomic
positions used in the simulation np1 times along "a",
np2 times along "b", np3 times along "c".
+--------------------------------------------------------------------

Variable: atomic_number(i), i=1,ntyp
Type: INTEGER
Default: 1
Description: Specify the atomic number of the species in CP trajectory and
restart file.
atomic_number(1) specify the atomic number of the first specie
atomic_number(2) specify the atomic number of the second specie
....
