Import EDAX EBSD Data (.ang)¶
Group (Subgroup)¶
IO (Input)
Description¶
This Filter will read a single .ang file into a new Data Container with a corresponding Image Geometry, allowing the immediate use of Filters on the data instead of having to generate the intermediate .h5ebsd file. A Cell Attribute Matrix and Ensemble Attribute Matrix will also be created to hold the imported EBSD information. Currently, the user has no control over the names of the created Attribute Arrays. The user should be aware that simply reading the file then performing operations that are dependent on the proper crystallographic and sample reference frame will be undefined or simply wrong. In order to bring the crystal reference frame and sample reference frame into coincidence, rotations will need to be applied to the data.
Default TSL Transformations¶
If the data has come from a TSL acquisition system and the settings of the acquisition software were in the default modes, he following reference frame transformations may need to be performed based on the version of the OIM Analysis software being used to collect the data:
- Sample Reference Frame: 180o about the <010> Axis
- Crystal Reference Frame: 90o about the <001> Axis
The user also may want to assign un-indexed pixels to be ignored by flagging them as "bad". The Threshold Objects Filter can be used to define this mask by thresholding on values such as Confidence Index > 0.1 or Image Quality > desired quality.
