10.36. Read Bruker Nano Esprit Data (.h5)
Group (Subgroup)
Import/Export (Import)
Description
This Filter will read a single .h5 file into a new 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.

Notes About Reference Frames
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. The recommended filters are:
If the data has come from a TSL acquisition system and the settings of the acquisition software were in the default modes, the 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 MAD > xx.
Note: If the X Step or Y Step within the HDF5 file for a scan is ZERO, those values will be set to 1.0 when the filter runs. This is needed as the user has no effective way to fix the HDF5 file. If the user needs a different spacing value, the user can utilize the Set Origin and Spacing filter.
