Tilia and Tilia-Graph were developed by Dr. Eric Grimm at the Illinois State Museum. Tilia is available free of charge; Tilia-Graph costs US$250.

TGView is used to print out .tgf files that we email to you to expedite report submission and/or to print another copy of the pollen diagram that we submit to you. Please remember that when you print the pollen diagram for yourself, you will need to apply the "A" characters that denote the presence of aggregates. That feature is not embedded in the Tilia program, but rather, is added by hand after printing the diagram.

How to Obtain and Install TGView

TGView is a Windows (95 and above) program that views and prints *.tgf files generated by the DOS version of Tilia*Graph. The program will read *.tgf files versions 1.10 through 1.26. An important feature of the program is that it will print to any printer supported by Windows. Because DOS drivers do not exist for many newer printers, this feature alleviates a major shortcoming of Tilia*Graph. The program also uses Windows TrueType fonts. TGView is the first step in the production of the full Tilia*Graph for Windows.

Download the latest version from:

Site: demeter.museum.state.il.us
Directory: /pub/grimm
File: TGV1311.EXE [released 18 March 2002]

You may point your Web browser to http://museum.state.il.us/pub/grimm/.

Instructions for installation

1. Copy TGV1311.EXE to a temporary directory. TGV1311.EXE is a self-extracting executable.

2. In the Windows Explorer, doubleclick on TGV1311.EXE to extract and run the setup program.

3. Select a temporary destination directory in the "TGView 1.3.1.1 Self-Extractor" dialog box. All setup files will be extracted into this directory. I recommend you choose a directory or subdirectory with nothing else in it, because you may delete these files after installation. This directory is not the directory in which TGView will be permanently installed. Click "Finish" when ready.

4. The standard InstallShield setup program will then run and lead you through the installation.

5. To make a set of installation diskettes for installation on another computer, see the Readme.txt file in the temporary directory.

6. The files in the temporary directory may be deleted after TGView is installed, but save these files if you think you may want to make a set of installation diskettes.

TGView Updates and Older .tgw Files

After upgrading to the latest TGView, the program works with old .tgf files, but old .tgw files give an error. TGView is still in development and there are so many changes between versions that maintaining backward compatibility is unfortunately just not practical. Backward compatibility will be maintained once a version of TGView with all (or about all) of the Tilia*Graph options is complete.
