rgpycrumbs.eon.ptmdisp

Identifies atoms in a structure file that do not match a specified crystal structure (e.g., FCC) and prints their 0-based indices to standard output. By default, the script is quiet. Use –verbose for progress messages.

Enum where members are also (and must be) strings

Functions

find_mismatch_indices(→ numpy.ndarray)	Analyzes a structure file with PTM, identifies the interstitial defect,
main(filename, structure, verbose, no_fcc_vacancy)	Analyzes FILENAME to find all atoms that are NOT the specified

rgpycrumbs.eon.ptmdisp.STRUCTURE_TYPE_MAP

rgpycrumbs.eon.ptmdisp.find_mismatch_indices(filename: str, target_structure: CrystalStructure, remove_fcc_vacancy: bool = False, view_selection: bool = True, selection_radius: float = 5) → numpy.ndarray

Analyzes a structure file with PTM, identifies the interstitial defect, and returns the indices of the interstitial atoms plus all atoms within a sphere of radius selection_radius.

rgpycrumbs.eon.ptmdisp.main(filename: str, structure: CrystalStructure, verbose: bool, no_fcc_vacancy: bool)

Analyzes FILENAME to find all atoms that are NOT the specified crystal structure type and prints their 0-based indices as a comma-separated list, suitable for use in other programs.
