Life is easy when STEM images are captured directly into DigitalMicrograph. However, where other interfaces are used, eg JEOL Microanalysis Station or JEOL's TEMCON interface, then images in other formats are obtained (TIFF and JEOL RAW DATA formats respectively). It is useful to be able to read these images into DM for calibration/measurement/analysis. TIFF files can be read in directly. However, JEOL RAW DATA (.jrd) cannot be opened directly. This format is actually a bitmap format (.bmp), so after changing the .jrd extension to .bmp, the files can be opened by DM (File/Open). This script will apply a calibration to the opened image - the only thing it requires is the magnification. The calibration factor for the particular scanning instrument must be obtained by either capturing an image with a scale bar built-in or imaging a feature of known dimension. This script contains extensive notes which explain how to read in .jrd files and how to do the calibration. This script can calibrate images from any type of scanning instrument - so SEM, AFM etc can also be used, provided the images are captured in a generic format which DM can read (TIFF, BMP etc).
Avoid JPEG if possible, as it introduces compression artefacts.
