class GDEFImporter

This class is used to read data from a *.gdf file (DME AFM) into python. This can be done like:

from gdef_reader.gdef_importer import GDEFImporter
impported_data = GDEFImporter(gdf_path)  # gdf_path should be a pathlib.Path to a *.gdf file

Methods defined:

• export_measurements

  Create a list of GDEFMeasurement-Objects from imported data. The optional parameter create_images can be used to show a matplotlib Figure for each GDEFMeasurement (default value is False).

• load

  Import data from a *.gdf file.

Properties defined:

• basename: Path.stem of the imported *.gdf file.

Single measurement

A *.gdf file can contain many AFM measurements. To handle a single measurement the class GDEFMeasurement is used. All the settings used during that specific measurement are stored in a GDEFSettings object.
