NCTR offers a powerful computer environment adapted to the unique needs of scientific research.  For routine administrative tasks such as word processing, spreadsheets, presentations and e-mail, NCTR relies on the FDA standard Microsoft Office suite.  Specific research needs are met by a variety of commercial and custom software including:

• AMPAC.  Semi-empirical Quantum Mechanics

• CODESSA.  Quantitative Structure/Activity Relationship (QSAR)

• Sybyl.  Computational Tool Kit for Molecular Design and Analysis

• MSI Catalyst. Rational drug design

• ISIS/Host.  Integrated Scientific Information System

• CSD.  Cambridge Structural Database

• EDKB.  Endocrine Disruptor Knowledge Base

• MultiGen.  Multi-Generation Experiment Information System

• WinLIMS.  Laboratory Information System

• SAS. Statistical Analysis

• Sudaan.  Software for the Statistical Analysis of Correlated Data

• SigmaPlot.  Scientific Graphics

• SigmaStat. Statistics

• AVS. Data Visualization

Scientific software is often available on a limited number of platforms; for this reason, NCTR maintains a wide variety of operating environments to support its administrative and research staffs, such as:

• Silicon Graphics workstations and servers

• IBM RS/6000 AIX

• Linux

• Windows 95/NT/2000

• Novell NetWare

• Compaq OpenVMS

The NCTR Help Desk and Training Center provide help in administrative and office applications.  The staff of the onsite Center for Computational Toxicology offers assistance in computational science to the NCTR research community.  An experienced software development staff is also on hand for the development of custom solutions where commercial software is unavailable.
