The Toxicity Relationship Analysis Program (TRAP) fits a sigmoidal toxic response versus exposure variable relationship to standard toxicity test data. It will analyze binary (e.g., survival) or continuous (e.g., growth, reproduction) biological effect variables as a function of any one-dimensional exposure variable. It will provide both best estimates and confidence limits for the parameters of the relationship and for the values of the exposure variable eliciting user-specified levels of effect. A Windows user interface provides for (a) entering data manually, from ASCII data files, and by copying from other software, (b) specifying options for the analysis and observing results, and (c) printing results and exporting them to other software. The program is a single executable file compatible with any Windows version and is accompanied by a help file containing operating instructions and information on the nature and performance of this analysis methodology.
The TRAP version 1.22 (3.0 MB) includes a readme file containing installation information, the TRAP executable, two compiled help files, and two example datafiles to check program operation.
