# REad Oxford Channel 5 Data File (.cpr/.crc)

## Group (Subgroup)

IO (Input)

## Description

This filter will read a single .cpr/.crc file pair into a new ImageGeometry. 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, inaccurate and/or wrong**. In order to bring the crystal reference frame and sample reference frame
into coincidence, rotations will need to be applied to the data. An excellent reference for this is the following PDF file:
[http://pajarito.materials.cmu.edu/rollett/27750/L17-EBSD-analysis-31Mar16.pdf](http://pajarito.materials.cmu.edu/rollett/27750/L17-EBSD-analysis-31Mar16.pdf)

### Default HKL Transformations

If the data has come from a HKL acquisition system and the settings of the acquisition software were in the
default modes, then the following reference frame transformations need to be performed:

+ Sample Reference Frame: 180<sup>o</sup> about the <010> Axis
+ Crystal Reference Frame: None

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 *Error* = 0. This will mark all scan points
that have Error=0 as TRUE, which means those scan points are valid for processing.

### Radians and Degrees

2D .cpr/.crc files have their angles in **radians**.

### The Axis Alignment Issue for Hexagonal Symmetry [1]

+ The issue with hexagonal materials is the alignment of the Cartesian coordinate system used for calculations with the crystal coordinate system (the Bravais lattice).
+ In one convention (e.g. EDAX.TSL), the x-axis, i.e. [1,0,0], is aligned with the crystal a1 axis, i.e. the [2,-1,-1,0] direction. In this case, the y-axis is aligned with the [0,1,-1,0] direction. (Green Axis in Figure 1)
+ In the other convention, (e.g. Oxford Instr, Univ. Metz software), the x-axis, i.e. [1,0,0], is aligned with the crystal [1,0,-1,0] direction. In this case, the y-axis is aligned with the [-1,2,-1,0] direction. (Red Axis in Figure 1)
+ This is important because texture analysis can lead to an ambiguity as to the alignment of [2,-1,-1,0] versus [1,0,-1,0], with apparent **30 Degree** shifts in the data.
+ Caution: it appears that the axis alignment is a choice that must be made when installing TSL software so determination of which convention is in use must be made on a case-by-case basis. It is fixed to the y-convention in the HKL software.
+ The main clue that something is wrong in a conversion is that either the 2110 & 1010 pole figures are transposed, or that a peak in the inverse pole figure that should be present at 2110 has shifted over to 1010.
+ DREAM.3D uses the TSL/EDAX convention.
+ **The result of this is that the filter will by default add 30 degrees to the second Euler Angle (phi2) when reading Oxford Instr (.ctf) files. This can be disabled by the user if necessary.**

This **Filter** will read a single .ctf file into a new **Image Geometry**, allowing the immediate use of **Filters** on the data instead of having to generate the intermediate .h5ebsd file.
