Analog Identification Methodology (AIM) Tool
The Analog Identification Methodology (AIM) is a downloadable software program that facilitates analog analysis and data identification in support of chemical assessment or read-across approaches to help scientists and chemical managers predict potential hazards of untested chemicals.
Key characteristics of the program include:
- Ability to conduct comprehensive structural analysis of chemicals using over 700 individual atoms, groups and super fragments indexed in a predefined database
- Uses structural analysis to match potential analogs from an inventory of over 86,000 chemicals with publicly available measured data and links to the data sources
- Ability to recode defined substitutions or exclusion rules for the refinement of analog search strategies
AIM software is available for free and is posted below as a downloadable software program without licensing requirements. Information on use and set-up is provided in the AIM User's Manual.
