VEC - Visual computing in Electron Crystallography

VEC is a program package developed by the Research Group on Methods of Solving Crystal Structures, Institute of Physics, Chinese Academy of Sciences. The program is mainly written in C++ and Fortran and is for running under MS Windows 95, 98, NT and 2000.

Main features:

• Preliminary processing of electron microscope images
• Indexing and measurement of electron difffraction patterns
• Determination of the defocus value from a single electron microscope image
• Direct-method resolution enhancement of electron microscope images
• Simulation of dynamical/kinematical electron diffraction patterns and electron microscope images
• 2-, 3- and 4-dimensional FFT
• 2-dimensional half-tone-graph display of 2-, 3- and 4-dimensional Fourier maps
• Contour mapping of 2-dimensional patterns
• Automatic determination of atomic modulation curves in an incommensurate modulated structure
