4. Circumstances behind the development of VESTAVESTA is originated from two GLUT- and GLUI-based applications, VICS and VEND, developed by R. A. Dilanian and F. Izumi during 2001-2004. They saw the light of day at the end of 2002 and, since then, continued their growth to be used widely in a variety of studies. However, we never get full satisfaction from their usability and performance. First, the combined use of VICS and VEND to visualize both crystal and electronic structures via text files is rather troublesome; on-the-fly visualization of these two kinds of images is highly desired. Second, their graphical user interface (GUI) is not very user-friendly because they are based on the old-fashioned toolkits, GLUT and GLUI, which have been no longer upgraded. Above all things, they require large system resources and source codes written in C language lack scalability owing to unrefined programming.
![Page 4: VESTA3Dvisualization_07oct](https://reader033.vdocuments.us/reader033/viewer/2022061605/55cf9b9d550346d033a6bd53/html5/thumbnails/4.jpg)
3D Visualization System VENUS2. Components of VENUS
The VENUS package contains five independent applications:
VICS: VIsualization of Crystal Structures VEND: Visualization of Electron/Nuclear Densities VESTA : Visualization for Electronic and STructural Analysis PRIMA: PRactice Iterative MEM Analyses ALBA: After Le Bail Analysis
That is, VICS and VEND visualize crystal structures and electron/nuclear densities, respectively. VICS delivers a feature to input/output standard input files, *.ins, of RIETAN-FP while VEND can input 3D density files, *.pri, created by PRIMA.
Koichi Momma has integrated VICS and VEND into a single application VESTA, adopting a cross-platform application framework wxWidgets and adding many new features. The processing speed, scalability, and quality of 3D images in VESTA have been considerably improved in comparison with VICS and VEND. Please use VESTA in place of VICS and VESTA. VESTA is separately distributed at JP-Mineral, where detailed information about VESTA is also obtainable.
PRIMA is a MEM analysis program to calculate electron densities from X-ray diffraction data and nuclear densities from neutron diffraction data. It was designed with M EM- based P attern F itting (MPF) in mind, as can be inferred from its name. ALBA is a program for the Maximum-Entropy Patterson (MEP) method, whereby Patterson functions in the unit cell can be determined from observed integrated intensities.
3. 3D visualization programs, VICS and VEND
VICS and VEND have been written in ANSI C for cross-platform portability, which allows us to port them from Microsoft Windows (hereafter abbreviated to Windows) to UNIX/Linux including Mac OS X.
With VICS, crystal structures are represented with ball-and-stick, space-filling, polyhedral, wireframe, stick, dot-surface, and thermal-ellipsoid models. Ball-and-stick and stick models may be enclosed in dot surface spheres with van der Waals radii. You will recognize that VICS is capable of representing anisotropic thermal motion better than ORTEP-III, which has no 3D-graphic capability.
Boundaries for drawing structures are specified in sophisticated ways similar to convoluting sphere and reiterative convoluting sphere in ORTEP-III.
![Page 5: VESTA3Dvisualization_07oct](https://reader033.vdocuments.us/reader033/viewer/2022061605/55cf9b9d550346d033a6bd53/html5/thumbnails/5.jpg)
Selection of objects (atoms, bonds, and coordination polyhedra) makes it possible to obtain fractional coordinates, translation vectors, equivalent positions, interatomic distances, bond angles, torsion angles, and information on coordination polyhedra (volumes, quadratic elongations, bond angle variances, and bond valence sums of central metals). Arrows indicating magnetic moments and positional shifts may be added to any selected atoms.
With VEND, electron/nuclear densities as well as wave functions and electrostatic potentials obtained by molecular-orbital methods are visualized as isosurfaces, bird's-eye views, and two-dimensional maps. Translucent isosurfaces and/or slices can overlap a ball-and-stick/stick model created by VICS.
Objects are rotated, expanded, shrunken, and translated fast in three dimensions, particularly in the presence of video cards accelerating the OpenGL API, e.g., those powered by the GeForce and RADEON graphic processing units (GPUs). Four different modes of rotating objects are supported: drag, push, click, and rotate automatically. In addition to crystallographic and electronic-state studies and education, we will take pleasure in manipulating 3D objects on personal computers. The development of VENUS was motivated by a desire to present the poor with the advanced graphic software. Neither graphics workstations nor commercial programs are now necessary for 3D visualization!
4. Structural data files for VICS
VICS can input and/or output files with the following formats:
1. Original format of VICS (input & output) 2. American Mineralogist Crystal Structure Database 3. Chem3D 4. CIF (Crystallographic Information File; input & output) 5. CrystalMaker text file 6. ICSD-CRYSTIN 7. CSSR (Crystal Structure Search and Retrieval) 8. CSD/FDAT 9. GAMESS input and 3D surface data files output by MacMolPlt 10. Gaussian Cube format 11.

19. XCrySDen XSF format 20. XMol XYZ (input & output) 21. asse 22. F01 for SCAT and C04D for contrd 23. MXDORTO FILE07.DAT
The feature of outputting *.ins allows us to read in crystal data files of various formats with VICS, simulate powder diffraction patterns, and carry out subsequent Rietveld refinements with RIETAN-FP. Heavy users of RIETAN will be very happy to input and output *.ins. After releasing VENUS, such a 3D visualization software package will be regarded as an indispensable tool for those who utilize a Rietveld-analysis program like RIETAN-FP. We must understand structural details not two-dimensionally but three-dimensionally!
5. 3D data files for VEND
VEND can input/output files storing 3D mesh data recorded with a variety of formats listed below.
1. Electron/nuclear-density files with the PRIMA format (binary). 2. Electron/nuclear-density files with the MEED format (text). 3. Patterson-function files output by ALBA for the MEP method. 4. Electron-density, electrostatic-potential, and wave function files with the
Gaussian Cube format 5. 3D surface data files obtained by MacMolPlt from GAMESS log files 6. Electron-density, electrostatic-potential, and wave function files obtained with

6. File converters
6.1 Alchemy
A file converter, Alchemy, for PRIMA was developed by Yukihiko Kawamura and Fujio Izumi. The Windows version of Alchemy, Alchemy.exe, is contained in folder 'Programs' as part of the VENUS system. For political and technical reasons, only a minor feature to
![Page 7: VESTA3Dvisualization_07oct](https://reader033.vdocuments.us/reader033/viewer/2022061605/55cf9b9d550346d033a6bd53/html5/thumbnails/7.jpg)
convert a MEM data set binary file, *.fos, output by RIETAN-FP into a MEM data set text file, *.mem, is currently opened to the public by giving two examples, fap and garnet, in Examples.zip; refer to Readme_Alchemy.txt in folder 'Alchemy' before using Alchemy.exe. The resulting file, *.mem, can be analyzed with PRIMA.exe to give a feedback data file, *.fba, and a 3D densities file, *.pri or *.den.
The Mac OS X version of Alchemy is also distributed; go to Subsection 11.3 to get it.
6.2 contrd and makec04d
Masataka Mizuno of Osaka University kindly wrote a Fortran program, contrd, to convert binary files, F09 and F39, output by SCAT for the DV-Xα method; method into text files storing 3D data. It is contained in an archive file, dvxa_v1_0*.zip, together with makec04d to create a template file of an input file, C04d, for contrd.
The two programs, contrd and makec04d, can be conveniently launched from an assistance environment for the DV-Xα method. It consists of many Hidemaru macros, helping us to launch a series of programs for DV-Xα molecular-orbital calculations and 3D visualization with VESTA. Its GUI enables us to utilize pulldown and pop-up menus, buttons, and shortcut keys. Note that this environment must be used in combination with the latest versions of dvscat programs and a molecular-orbital calculation system, eduDV, for education.
To download the archive file of the above assistance environment, go to Ball & stick model of double carbon nanotubes (99 KB)

8. Super-fast program, PRIMA, for MEM analysis
8.1 Improvements in PRIMA
The award-winning technology of MPF is an alternative to a traditional approach, i.e., Rietveld analysis, to structure refinement from powder diffraction data. Crystal structures are represented not with structure parameters in Rietveld analysis but with electron/nuclear densities in MPF. A fast MEM analysis program is desired in MPF where MEM analysis and whole-pattern fitting are alternately iterated until convergence.
Till lately, we had been utilizing MEED for the MEM analysis of structure factors obtained experimentally from X-ray and neutron diffraction data. After making every effort to speed up MEM analysis, we at last completed our own Fortran 90 program PRIMA, the state of the art in MEM analysis. MEED is now obsolete because of its serious bug and sluggish speed.
PRIMA has been written from the ground up in Fortran 90, which enables us to create storage for allocatable arrays dynamically. It is thoroughly optimized for personal computers equipped with Intel Pentium 4 processors and operated with Windows. Nonlinear single-pixel approximation (never use this for a small number of reflections), full use of space-group symmetry, and adjustment of Lagrangian multipliers further accelerate MEM analysis. PRIMA is applicable to MEM analysis from neutron diffraction data of compounds containing elements whose coherent-scattering lengths are negative, e.g., H, Li, Ti, and Mn.
8.2 How to use PRIMA in combination with RIETAN-FP and VEND
PRIMA makes it easier to modify a structural model in the course of Rietveld analysis. In a user input file, *.ins, set NMODE at 0 and NMEM at 1, and input various parameters for MEM analysis. Run RIETAN-FP to create a MEM data set file, *.fos. Fo(Rietveld) data in this file are analyzed by PRIMA, which creates a 3D density file, *.pri, and a feedback data file, *.fba, storing Fc(MEM)'s. VEND serves to input *.pri to visualize 3D electron/nuclear-density distribution. Your structural model is rebuild after close checking of the density image, if necessary (so-called MEM/Rietveld method). Thus, PRIMA is now regarded as a must-have item for Rietveld analysis on PCs.
The MEM/Rietveld method is a halfway approach to determination of electron/nuclear densities from X-ray/neutron powder diffraction data because the Fo(Rietveld)'s are more or less biased toward the structural model in the Rietveld analysis. For this purpose, MPF is far superior to the MEM/Rietveld method.
Nothing is so difficult as MPF. At first, whole-pattern fitting (w.p.f.) is carried out from the Fc(MEM) data in *.fba. Simply set NMODE at 2 and NMEM at 1 in *.ins, and then run RIETAN-FP. Note that all the structure parameters in *.ins must have been updated on the analysis of X-ray diffraction data because contributions of anomalous scattering to structure factors are calculated from them. Of course, we should change the ID(I)'s of the
![Page 9: VESTA3Dvisualization_07oct](https://reader033.vdocuments.us/reader033/viewer/2022061605/55cf9b9d550346d033a6bd53/html5/thumbnails/9.jpg)
structure parameters into zero and comment out linear constraints, if any. On repartition of observed diffraction intensities after the w.p.f., structural information contained in (nearly) isolated reflections effectively reduces the bias toward the structural model in the Rietveld analysis. Fo(w.p.f.) data in the resultant binary file, *.fos, or a text file, *.mem, converted from it are analyzed by PRIMA to get *.fba as well as a 3D densities file, *.pri (binary file) or *.den (text file).
In such a way, w.p.f. and MEM analysis are alternately repeated until R factors (usually Rwp) in the former no longer decrease (REMEDY cycles). The bias to the structural model reduces with increasing number of cycles. Throughout the REMEDY cycles, the total number of electrons (X-ray diffraction) or the total coherent-scattering lengths (neutron diffraction) in the unit cell is fixed at that obtained from the chemical formula and Z. Thus, electron/nuclear-density distribution affording the best fit to the observed diffraction pattern can be determined by MPF.
Refer to a PDF file, PRIMA.pdf, entitled "Super-fast Program, PRIMA, for the Maximum-Entropy Method" to learn further details in PRIMA.
9. ALBA for the MEP method
ALBA is a Fortran 90 program for the MEP analysis of observed integrated intensities (1) estimated by the Le Bail method from powder diffraction data and (2) determined from single-crystal diffraction data. The name of the program originates from the most significant feature of the program; that is, MEP analysis is carried out After Le Bail Analysis.
Only a program for MEP analysis from integrated intensities obtained by the Pawley method has hitherto been developed by David of RAL. No MEP analysis program has yet been distributed on the Web. Therefore, we built a powerful MEM engine into ALBA, making alterations to that of PRIMA. Thus, ultra-fast MEP analysis is possible with ALBA.
Integrated intensities of overlapped reflections in powder diffraction data are, more or less, improved by the sophisticated MEP method, which is favorable for ab initio structure analysis from powder diffraction data.
ALBA is used in combination with a multi-purpose pattern-fitting system RIETAN-FP or EXPO for ab initio structure analysis from powder diffraction data by a direct method.
ALBA outputs a binary file, *.pri, storing 3D Patterson functions, which are, in turn, visualized with VEND, as described in Section 5. The resulting 3D images in the unit cell serve for construction of an initial structural model by the heavy-atom method.
![Page 10: VESTA3Dvisualization_07oct](https://reader033.vdocuments.us/reader033/viewer/2022061605/55cf9b9d550346d033a6bd53/html5/thumbnails/10.jpg)
Most Rietveld-analysis programs incorporate the feature of Le Bail analysis because of the ease with which it can be implemented in this type of software. ALBA allows us to improve integrated intensities obtained with them for overlapped reflections, adding value to them.

V_Sim is a software application that will alllow you to visualize atomic structures such as crystals, grain boundaries and so on (either in .d3 format as defined by F. Lan�on, or in plain text format).
The rendering is done in pseudo-3D with colored sphere to represent the atoms.
The user can interact through many functions to choose the view, the size of the atoms, their color, the background color, the type of fog...
Much of it is detailled in the user guide. Moreover V_Sim allows to export the view as image in GIF, PS or more formats.
V_Sim uses GTK2 (lib and dev files version 2.4 or greater) and OpenGl (lib and dev files), no other dependencies are required. It is programmed in C and is aimed to run on *nix systems and compile also on Win32 platforms.
