MacTempasX

MacTempasX Version 2 represent a major upgrade of MacTempas. The program has been expanded to include a huge number of new features. In addition to the basic image/diffraction HRTEM capabilities, STEM and CBED calculations have been included. The program now includes both basic and advanced image processing capabilities as well as quantitative image comparison and structure refinement.
