A method of EBSD.

read an EBSD map from a supported vendor file or a text table

Syntax

ebsd = EBSD.load('map.ang')
ebsd = EBSD.load('map.ctf', grid=False)

Description

This calls loadEBSD with the same arguments. The file format is selected from the extension unless interface is given. Phase information, orientations, positions and available pixel properties are read together; complete scans are returned on their grid by default. For text-table column definitions and import corrections, consult loadEBSD. Use inspectEBSD to inspect file metadata before importing.

Input

fname input filename
args positional options accepted by loadEBSD
kwargs keyword options accepted by loadEBSD

Output

ebsd EBSD map

Example

Read the Forsterite vendor file directly and draw its phase map. The sample file is downloaded and cached on first use. The Euler correction shown here is specific to this file.

import matplotlib.pyplot as plt
from mtex import EBSD, mtexdatafile, rotation, vector3d, degree, plot

filename = mtexdatafile('forsterite', verbose=False)
correction = rotation.byAxisAngle(vector3d.X, 180*degree)
ebsd = EBSD.load(filename, eulerCorrection=correction)
print(ebsd)
plot(ebsd, refFrame='on')
plt.show()

Inspect the phase list and the reference-frame indicator after import. For another file, choose the format options and Euler correction from its acquisition convention.
