To import an EBSD acquisition from HKL Channel5, EBSD-Image requires a ctf file. The result is an EBSD multimap. From the importer wizard, the user can also convert the diffraction pattern images to a smp file. For a typical map of around 50,000 pixels, the conversion takes about 10 minutes.
Generate a ctf file
Open the HKL Channel 5 Manager
Open an EBSD acquisition project (cpr file)
From the Project menu, select Export and as Channel Text File (*.CTF)....
Select the ctf file to import.
After clicking Next, it may take a few seconds before the next page of the wizard is displayed. During that time, the header containing the information about the EBSD acquisition are loaded.
Some metadata related to the EBSD acquisition can not be loaded directly from the ctf file. These information are optional.
Working distance: Working distance used for the EBSD acquisition.
Calibration: Calibration of the camera. The calibration is related to the position of the camera with respect to the sample. It consists of two parameters: the pattern center and the detector distance. All values are expressed as a fraction of the camera's width. The (0, 0) position of the pattern center is defined as the center of the diffraction pattern.
The phases information (unit cell parameters, atom positions and symmetry) cannot be loaded from the ctf since the atom positions are missing. Therefore, the user must create the phases used in the ctf manually. The number of phases and their respective name in the ctf is given in the warning section of the wizard page. The list of current phases must match the number of phases in the ctf as well as their order.
For more information on how to create a new phase, please refer to the wiki page Phase.
This wizard page is to automatically convert the diffraction patterns saved during an HKL acquisition to a smp file. If this step is skipped, only the information in the ctf file will be converted to an EBSD multimap. If the diffraction patterns images have not being moved since their acquisition by HKL Flamenco, the wizard can automatically find where the images are located, however it is often easier to manually select the folder containing the images (typically ProjectXXXImages). Be careful not to enter the folder when you are selecting it since the listing of the images files by the operating system is a lengthy process.
Finally, the location where to save the EBSD multimap and smp file must be specified. Please note that only the location and name of the EBSD multimap is required since the smp file will be saved in the same folder with the same name; only the extension is changed to smp.
