BMDS 2.4 and Related Software/Documentation
BMDS VERSION 2.4 SYSTEM REQUIREMENTS
This BMDS 2.4 final version is being released for use by risk assessors as the official BMDS system. BMDS requires at least 16 Megabytes of RAM and should run in Microsoft Windows 2000, NT, XP, Vista, and 7, however only operation in Windows XP has been fully tested at this time. BMDS Version 2.4 can be installed in any folder that the user has create/read/write privileges.
BMDS also requires the latest version of .NET (4.0 or later). If your machine is set up to allow or be notified of downloads of Microsoft software, then it is likely that that version of the .NET framework is already installed. Otherwise, the latest version of .NET for client desktops can be downloaded from http://www.microsoft.com/net/downloads .
To run the toxicodiffusion model included in Version 2.4, you must install version 2.6.2 or later of the R statistical software to your computer (go to http://www.r-project.org/ for more information).
CHANGES TO BMDS INSTALLATION PROCEDURE
Previous BMDS versions (BMDS 2.1.2 or earlier) used a SETUP.EXE file to create the BMDS directory, add icons to the Programs menu, provide an entry in the Add/Remove Programs control panel, and so on. However, BMDS 2.4 is being distributed as a compressed ZIP file and does not employ any automated install programs or wizards. The implications of this change are that (a) user's do not need administrative rights to install BMDS 2.4, (b) BMDS Version 2.4 can be installed in any folder that the user has create/read/write privileges, and (c) users will need to create their own shortcuts to the program (e.g., on their computer's desktop).
If you already have a version of BMDS installed on your computer, read the section CONSIDERATIONS FOR PREVIOUS BMDS INSTALLATIONS & UNINSTALLING. If you're new to BMDS, go to the section INSTALLING BMDS and then read the instructions in the section AFTER INSTALLING BMDS for creating a desktop shortcut.
CONSIDERATIONS FOR PREVIOUS BMDS INSTALLATIONS & UNINSTALLING
It is not necessary to uninstall previous versions of BMDS to install and run BMDS 2.4. However, if you want to uninstall previous versions of BMDS, it is recommended that you retain the directory structure for the folders where your previous model runs reside in order to maintain the functionality of previous sessions.
Installing BMDS 2.4 and Wizard 1.8
To install BMDS:
- Click here to save (download) the zip file for BMDS 2.4 and Wizard 1.8 (15.8MB)
- Locate the BMDS zip file you downloaded. Typical locations for file downloads are the Windows Desktop or the Download directory in My Documents.
- In Windows Explorer, double-click the downloaded .zip file. Drag and drop the BMDS240 folder from the .zip file to the directory of your choice on your computer (for example: C:\USEPA). The new Excel-based Wizard templates will work with BMDS 2.4 installed in any directory. Please use the "Problem Report" feature listed in the "Help" menu of BMDS 2.4 or contact us using our Help Desk Form if you experience installation problems or have questions.
AFTER INSTALLING BMDS
Please read the Readme 2.4.pdf file in your main BMDS directory for additional information (e.g., regarding verification of the installation and any known bugs in the current version).
You may find it more convenient to run BMDS from a desktop shortcut icon. Here's how to create one:
- In Windows Explorer, navigate to the BMDS240 folder.
- Right-click the BMDS240.exe file. A context menu appears.
- Click Send To. A submenu appears.
- Click "Desktop (Create Shortcut)". Windows creates a shortcut to the file on your desktop.
Once in the system, use the Help feature for further assistance. If you have problems or concerns, please use the "Problem Report" feature listed in the "Help" menu of BMDS 2.4 or contact us using our Help Desk Form .
To determine whether BMDS is properly loaded on your computer, choose "File" from the menu at the top of the BMDS program, then "Open," then "Dose Response Session (.ssn)." The Window should open to the BMDS SessionFiles folder. Select and open any .ssn file (e.g., Cancer-BMR10.ssn). When the Session screen appears, click the "Save As" button and resave the session under a different name (e.g., Cancer-BMR10-test.ssn; you can delete this file later). Then click the "Run" button on the resaved Session screen. When the plots and summary report appear, click on "File" at the top of the summary report screen and then "Export to Excel." Pre-selected summary report data should export to several Excel worksheets, with the "Dichotomous Format" or "Continuous Format" worksheet in the initial view. If you are able to complete these steps without extraordinary (i.e., not normal model error messages), BMDS is likely to have been installed properly and completely.
Registering: Registration is not required to download the software.

We also offer the C source code files for the individual models used in the BMDS system to reviewers/programmers that might be interested in performing an in-depth analysis of the model algorithms and features. We welcome, in fact encourage, comments, recommendations, suggested revisions, or corrections, through our Help Desk Form .
Note: To keep your BMDS system current, check the BMDS website (http://www.epa.gov/ncea/bmds) periodically for updates to the software or help manual.
