Prepare needed files for NEB
Provides several regimes controlled by *search_type* flag:
- existing_voids - search for voids around atom and use them as a final position
- vacancy_creation - search for neighbors of the same type and make a vacancy as a start position
- interstitial_insertion - search for two neighboring voids; use them as start and final positions
by inserting atom *atom_to_insert*
- None - just use st and st2 as initial and final
###INPUT:
- starting_calc (Calculation) - Calculation object with structure
- st (Structure) - structure, can be used instead of Calculation
- it_new (str) - name for calculation
- st_end (Structure) - final structure
- i_atom_to_move (int) - number of atom for moving starting from 0;
- *mag_config* (int ) - choose magnetic configuration - allows to obtain different localizations of electron
- *replicate* (tuple 3*int) - replicate cell along rprimd
- i_void_start, i_void_final (int) - position numbers of voids (or atoms) from the suggested lists
- atom_to_insert (str) - element name of atom to insert
- atom_to_move (str) - element name of atom to move
- it_new_folder or it_folder (str) - section folder
- inherit_option (str) - passed only to add_loop
- inherit_magmom (bool) - if True than magmom from starting_calc is used, else from set
- end_pos_types_z (list of int) - list of Z - type of atoms, which could be considered as final positions in vacancy creation mode
- calc_method (list)
- 'neb'
- 'only_neb' - run only footer
- x_start, x_final (array) - explicit xcart coordinates of moving atom for starting and final positions, combined with atom_to_insert
- xr_start, xr_final (array) - explicit xred
- rep_moving_atom (str)- replace moving atom by needed atom - can be useful than completly different atom is needed.
- upload_vts (bool) - if True upload Vasp.pm and nebmake.pl to server
- run (bool) - run on server
- old_behaviour (str) - choose naming behavior before some date in the past for compatibility with your projects
'020917'
'261018' - after this moment new namig convention applied if end_pos_types_z is used
- add_loop_dic - standart parameters of add()
- params (dic) - provide additional parameters to add() # should be removed
###RETURN:
None
###DEPENDS:
###TODO
1. Take care of manually provided i_atom_to_move in case of replicate flag using init_numbers
2. For search_type == None x_m and x_del should be determined for magnetic searching and for saving their coordinates
