Installation Guide & Tips

  1. make sure that your system has been installed with JavaVM (JRE for PC/Windows OS from, and the PATH of  “java.exe” must be accessible by the system from any directory/folder. Mac OS X users should be fine with OpenJDK6 or 7 or both as bundled with Mac OS X. Oracle Java VM may also work if it is installed properly.

  2. unzip “boomer.exe” (and it's freeware!) from .zip file which can be downloaded from Boomer website. Remind you that you should download the appropriate version for your system.  The latest version of BOOMER is v3.3.1 gFortran ver.. (Apr. 2006). For Mac OS X users, please download boomer337.pkg to install. And after installation find Boomer at folder of "/usr/bin"

  3. Unzip the .zip file and click JGuiB.jar for both PC/Windows and Mac OS X.

  4. For users of linux (some linux distros; not all of them!) ONLY: please move the following folders/files to your 'home/username'- 'UserDefModels', 'Examples', and 'BuildInModels' plus one pdf file (JGuiB User's Guide.pdf); otherwise, you will not see anything under "PK/PD Modeling" (the first Tab). For linux distros based on 'xfce' display manager, such as Xubuntu, it may not be required to do so. Anyway, if there is anything wrong, just switch these folders back. Also, for better text display of output file for ubuntu, please make sure that your system have 'DejaVu Sans Mono' font. We use 'DejaVu Sans Mono' font to display output. You can open any application such as'gedit' or 'AbiWord' under your ubuntu and go to Preferences to see if 'DejaVu Sans Mono' font is on the list. Just make sure about it.

  5. Please note that the generated output file will be saved as 'ouput.OUT', which can be found in the folder where the project file is located. However, users need to save the project (top menu -> File -> Save project) first after running a project; otherwise, the output file cannot be saved as expected.
