Since 'n_orbitals' can be a 2D array in case of spin-polarized
calculations, one should use 'numpy.max' instead of 'max' to
extract the maximum number of bands.
In the new version of VASP LOCPROJ contains the eigenvalues and
Fermi weights. Also, during a charge self-consistency calculation
the file EIGENVAL is not written at intermediate iterations. It is,
thus, preferential to use LOCPROJ to get the named data.
At the moment, EIGENVAL will still be used if it is complete but
in the future this dependence should be removed completely.
The band indices should be converted to Fortran convention,
i.e. starting from 1, in the output files because the are
used in the density matrix file which is read by a Fortran code.
The format of LOCPROJ has been modified again (in VASP 5.4.2
build from Dec 02, 2015).
Now, there is an additional line before each projector block
providing the spin, k-, and band indices, as well as
eigenvalues and Fermi weights.
Scripts 'run_plovasp.sh' have been replaced by a template in which
the path must be set by the user.
Also, .gitignore has been added to example 'lunio3'.
It was incorrect to ascribe VASP atomic sort to corr_shell['sort'],
the latter having a different meaning. According to the terminology of
Wien2k a sort determines an equivalence class of atoms.
Since the implementation at the moment does not support symmetries
the atom index is now used as a 'sort' index to make sure that all shells
remain inequivalent.
The files from the original vasp-interface repository are reshuffled in
accord with the directory structure of dft_tools. Some of the directories,
such as 'test' (unit tests for the interface), 'examples' (simple examples for
the development purposes) are temporarily placed into 'python/vasp' directory
to avoid confusion with integral tests and examples of dft_tools.
Import of 'json' is fixed to conform python distributions without
'simplejson'.
Also, the full path is used for 'converter_tools' for the moment while
'vasp_converter' is not part of 'dft_tools'.
It seems that not all distributions of python come with a 'simplejson' module.
Now, if this module is not found the import falls back to module 'json'.
At the moment, symmetries are not supported by the interface.
Instead, some dummy parameters are generated and the symmetry is turned off.
'misc_input' is only partially implemented because it contains
some data which is not required for the correct functioning of DftTools.
This preliminary version is untested and might not even run.
Here, almost all relevant input (apart from symmetries and miscellaneous)
is implemented and conventions adpoted in DftTools are accomodated.
Method 'nelect_window()' now correctly takes into account a subset
of bands selected by the energy window.
Also, the number of electrons is now output to a '*.grX' file.
The data for a projected shell (output to a '*.pgX' file) contains
now the ion sort corresponding to this shell.
Also, 'check_data_consistency()' was fixed by correcting the
reference to list 'type_of_ion' (which is now copied to ElectronicStructure).
Added a check to 'check_data_consistency()' that verifies
that each shell contains only one sort of ions.
Also added a non-functioning test (implementation is commented)
for the function.
It requires a full set of VASP files for an example with multiple atom sorts.
'read_data()' is a generator interpreting a file as a sequence of
floats. Lines starting with '#' are ignored.
'read_header_and_data()' reads the header string until a line
"# END ...", initializes a generator 'read_data()', and returns
them.
'vasp_converter.py' is based on the existing 'wien2k_converter.py'.
Methods 'read_header_and_data()' and 'read_data()' for reading input files
are added. The first method returns a JSON-header and a generator 'read_data()'
returning floats from the plain-data part of the file.
'main()' now calls a function 'output_as_text()' responsible for storing
both a ctrl- and plo-files ('ctrl_output()' and 'plo_output()', respectively).
Added function 'ctrl_ouput()' which stores data common for all correlated
shells into a file '<basename>.ctrl'.
At the moment, only a very basic header is output.
The signature of 'plo_output()' is also modified to include an instance
of class 'ElectronicStructre' containing important information on
the lattice structure, Efermi, and k-points.
Parsing of two optional parameters (BASENAME and EFERMI) from section [General] from the config-file
is implemented. If this section is not found the parameters are set to their
default values, which is 'vasp' for BASENAME and nothing for EFERMI.
Appropriate test is added to the 'inpconf' test suite.
