# Z-matrix Editor KUMI''

under construction, part of this page is written in japanese. Key word: molecular modeling, molecular builder, Z-matrix editor

## What is KUMI'' ?

When you perform the molecular orbital calculation such as Gaussian94, you have to make input file with molecular structure. It may take some effort to imagine the molecular structure described by Z-matrix, even if Z-matrix is powerful and useful to represent the structure of the molecules.

Then we make the Z-matrix Editor KUMI'' for visually constructing molecules by means of Z-matrix.

### Features of KUMI''

Z-matrix Editor, KUMI'' has the following features:
• Little restrictions on platform for running KUMI''. Because, it runs on Unix/X11 system, and it is using a Motif library.
• Easy to use for beginners in computer. Because, it is the application with a multi-window-type graphical user interface (GUI).
• You can construct a molecular structure through Z-matrix, and show it graphically.
• You can use labels for structural parameters, such as bond length, bond angle, and dihedral angle.
• You can rotate and enlarge the molecule which is displayed on screen.
• You can confirm the structure of the molecule by immediate view on screen, when you change the Z-matrix and/or value of labels.
• You can use the output data file of KUMI'' as the input structure for Gaussian94, MOPAC, etc.

## Platform

### Running KUMI''

The program KUMI'' itself works on the Unix/X11 based workstations. It uses a Motif-2.0 widget set for its graphical user interface (GUI).

The program can be compiled and run on the following systems:

• NEC/UP4800, Unix SVR4 (owani8: Center for C&C, Hirosaki Univ.)
• COMTEC4D, IRIX (picasso: Center for C&C, Hirosaki Univ.)
• AT-compatible machine with PC-UNIX (FreeBSD/XFree86)

### For Building Molecules

One of the systems listed below are required for building-up the molecules using KUMI''.
• Computers with X Window System
• X terminal
• PC (Windows and/or Mac, etc.) with X-server software (for example: eXodus, and MI/X, etc.)
Color display is mostly preferable, while you may use this program with monochrome (grey scale) display. This program is not adapted to 2-bit display.

Please send me some comments and suggestions for KUMI''. Bug report is also preferable.

## How to install it ?

It is very easy to install KUMI''.

1. Extend the package distributed here by gunzip + untar.
2. Type make' in the kumi/ directry. (.' must be included in your PATH)
3. Type make install' as root.
4. Set environment variable KUMIDIR as /usr/local/share/kumi/', because the KUMI.Template file is put there.

When you use the executable binary for FreeBSD 2.x, which is included in the tar-gzip archive.

1. Gunzip + untar the archived package.
2. Put the file kumi/bin/kumi-s-1.0-freebsd2.x' on somewhere in PATH.
3. Put KUMI.Template' on somewhere indicated by KUMIDIR.

When you build and use kumi on the other systems.

1. Gunzip + untar the archived package.
2. Move to the directory kumi/' and type make'. (.' must be included in your PATH)
3. Type make install' as root, then kumi' will be installed in /usr/local/bin/'.
4. Set environment variable KUMIDIR as /usr/local/share/kumi/', because the KUMI.Template file is put there.

## How to use it ?

Detailed instructions for usage are written in the documents:
(PS file, gzip 250kB, Only JAPANESE version is available, now.)

Selecting pull down menu at main window, the sub-windows of a molecular viewer and an input form of Z-matrix will be opened. You can see the molecular structure from any direction you wish. When you input the Z-matrix of the molecule, the structure of it is immediately shown. Then you can build the molecule as what you want.

Instead of CLICK menues by mouse, you can operate KUMI' by short-cut key. To open pull-down menu, push [ALT]+<key> followed by <key>.
For example, you want to do -[Z-matrix] then type [ALT]+e z, so the edit window of Z-matrix will be appeared.
Or, after opening pull-down menu by [ALT]+e, select the item [Z-matrix] by arrow keys and push [Enter] or [Space], then the window will be opend.
