The team that created STRmix– forensic software used to resolve mixed DNA profiles previously thought to be too complex to interpret–is launching FaSTR DNA, expert forensic software that rapidly analyzes DNA profiles and assigns a Number of Contributors (NoC) estimate.
Designed by scientists for scientists, FaSTR DNA expedites the analysis of raw data generated by genetic analyzers and standard profiling kits. It does this by combining an intuitive, user-friendly graphical interface with easily understandable and laboratory-customizable rules.
FaSTR DNA also implements the use of artificial neural networks (ANN) for peak classification independent of and in parallel to the forensic analyst.
"STR DNA profiling analysis is a process of identifying alleles at highly variable sites on the chromosome," explains Meng-Han Lin, Senior Scientist, STRmix Team.
Recognizing the need for speed, accuracy, and simplicity, particular attention has been paid in developing FaSTR DNA to simplifying the analysis procedure. Doing so enables reliable results to be achieved with minimum effort.
FaSTR DNA's built-in Number of Contributors (NoC) estimator allows seamless integration with STRmix™ (when in use) for even greater speed and efficiency in analysis and interpretation of complex mixed DNA profiles.
FaSTR DNA works by applying a set of fully configurable rules to analyze most DNA profiles automatically. Because DNA analysis is so complex and the rules cannot resolve all profiles without the intervention of a DNA analyst, however, FaSTR™ DNA signals when human intervention is required. It then records and highlights changes made by the analyst. FaSTR DNA's analysis algorithms are conceptually adapted from the proven approach of OSIRIS DNA (National Center for Biotechnology Information).
In its early release phase, FaSTR DNA will be available only to select STRmix users. Sales to a wider audience are expected to be available in the near future.
