SciFiReaders.readers.microscopy.em.tem.dm_reader.DMReader

class SciFiReaders.readers.microscopy.em.tem.dm_reader.DMReader(file_path, verbose=False)

Bases: Reader

Reader of Digital Micrograph image and spectroscopy data

This reader reads (attribute read) all the different data in the file and returns it as a dictionary of sidpy.Datasets

Parameter:

file_path: str

filepath to dm3 or dm4 file.

Return:

datasets: dict

dictionary of sidpy datasets

param file_path:

Path to the file that needs to be read

type file_path:

str

self._input_file_path

Path to the file that will be read

Type:

str

Notes

• This method will check to make sure that the provided file_path is indeed a string and a valid file path.

• Consider calling can_read() within __init__() for validating the provided file

raises FileNotFoundError:
