Input files¶
Structure file¶
The valid formats for structure file are that for VASP and cif format. In the cif files, symmetry operator (_space_group_symop_[] or _symmetry_equiv_[]), atomic label (_atom_site_label), occupancy (_atom_site_occupancy) and fractional positions (_atom_site_fract_[]) must be included. The name of structure files must be formatted as name.cif or POSCAR_name where tag is used for identification.
VASP structure file format:
Primitive Cell 1.000000000 0.0 2.714895 2.714895 2.714895 0.0 2.714895 2.714895 2.714895 0.0 Si 2 Selective dynamics Direct 0.5 0.5 0.5 T T T ! Si1 0.75 0.75 0.75 T T T ! Si1
Configuration¶
All of parameters can be tuned in the configuration file as following. The detail for each parameter is explained in Configuration.
config.yaml:
