BMDS Version 2.1.1
This BMDS 2.1.1 final version is being released for use by risk assessors as the official BMDS system. BMDS requires at least 16 Megs of RAM and will run in Windows XP and Windows Vista.
If you already have BMDS 2.1 (Build 52) installed, you need only download and unzip this small patch file and run the "BMDS211Patch55.msi" contained therein. This procedure does not involve registry access, and should allow you to upgrade BMDS without the need for assistance from your local IT/computer support department.
If you have BMDS 2.0 or BMDS 2.1 beta installed, you will need to uninstall those versions of BMDS before installing version 2.1.1 (see details below).
If you have BMDS 1.4.1 (or earlier versions) or do not have BMDS installed on you computer, you can simply download and install version 2.1.1 as described below.
To download and install BMDS 2.1.1 on you computer:
- Click here to save (download) the zip file for BMDS 2.1.1 (11 MB)
- Unzip (extract) the zip file. Two files should appear, "setup.exe" and "SetupBMDS211R55.msi"
- Double-click on "setup.exe" and follow the instructions
- BMDS 2.1.1 icons will be placed on your desktop and in your Start Menu. Run the program by double-clicking on the BMDS icon
You are now ready to run BMDS 2.1.1. You should be able to run the program by double-clicking on the BMDS icon on your desktop or
selecting the BMDS program from among the programs listed in your Windows "Start" directory. Once in the system, use the Help feature
for further assistance. Please read the Readme.txt file in your C:\USEPA\BMDS21 directory for additional (e.g., regarding verification
of the installation and any known bugs in the current version). If you have problems or concerns, please contact us using our
Help Desk Form.
Uninstalling previous versions of BMDS (e.g., versions 2.0 or 2.1 beta): To uninstall the BMDS application, go to Control Panel, open the Add or Remove Programs utility and click on the "Remove" button. Simply deleting the application files doesn't uninstall the software. Note: If the user doesn't have the proper rights in the computer, the "Remove" button will not be shown and the user should uninstall BMDS by restarting the original setup.exe file and then choosing "Remove Benchmark Dose Software."
Note: Registration is not required to download the software. However, if you would like to receive a notification when new
releases or important information becomes available, please register on the download page. 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, the our
Help Desk Form
or by e-mailing bmds.ncea@epa.gov. Written comments can be addressed to Dr. Jeff Gift, EPA
(MD-52), Research Triangle Park, NC 27711.
Note: To keep your BMDS system current, check back periodically and either repeat the above steps, or go to our model file updates page to download smaller, individual files that have been updated since your last download.
Toxicodiffusion model documentation
To run the Toxicodiffusion model that is in BMDS 2.1.1 you will need to also install version 2.6.2 of the R statistical software to your computer (http://www.r-project.org/) and the R(D)Com interface to R (Note that you do not need to install R to run any of the other BMDS Models). At this time, the toxicodiffusion model within BMDS is not compatible with more recent verions of R or R(D)COM.exe. The next version of BMDS will correct this issue.
For a complete description of the beta toxicodiffusion model contained in BMDS 2.1.1, download the beta toxicodiffusion model documentation file (734 KB).
Ten Berge model documentation
The beta ten Berge model has been incorporated into the BMDS 2.1.1 interface. The following beta ten Berge documentation and reviewer comment files are available for downloading.
