Workshop DNAxs/DNAStatistX: A software suite for the data management and probabilistic interpretation of DNA profiles on 28 May 2020 (Thursday)
Workshop teacher: Corina Benschop, Netherlands Forensic Institute
Corina Benschop is a forensic research scientist employed at the Netherlands Forensic Institute since 2005. She has a background in molecular biology and a PhD degree in Forensic Genetics. Primarily, Corina performs and supervises research studies regarding the interpretation of complex DNA-profiles. She is involved in the development and validation of methods (e.g. LoCIM, LRmix Studio, SmartRank, DNAxs, DNAStatistX), implementation into forensic casework, defining guidelines for best practice, and providing training in many (international) mixture interpretation workshops.
Aim: To provide participants with knowledge on the DNA eXpert System, DNAxs, and its probabilistic genotyping module DNAStatistX.
Target Group: Law enforcement forensic experts – experienced reporting officers who deal routinely with DNA profiling evidence and are required to interpret complex mixtures in casework.
General Learning Outcomes:
- Insight in the current and future features of the DNAxs software and how these can aid in the analysis and interpretation of DNA profiling data in forensic casework
- Understand the differences between the classical likelihood ratio principle, semi-continuous (e.g. LRmix Studio) and continuous probabilistic genotyping models.
- Discuss validation, guidelines and troubleshooting when using the continuous model DNAStatistX.

DNAxs is a DNA eXpert System which enables automatic comparison of sets of DNA-profiles, provides summary statistics on allele numbers and genotype reproducibility and assists reporting officers in interpreting DNA profiling results. A continuous model, denoted DNAStatistX, based on EuroForMix (www.euroformix.com) is integrated into this package. The DNAxs software will be demonstrated as well as the integrated and stand-alone version of DNAStatistX.
The stand-alone version of DNAStatistX is open source and freely available alike EuroForMix.
DNAxs and DNAStatistX were developed at the Netherlands Forensic Institute, alike e.g. LRmix Studio and SmartRank. DNAxs v2.0 was partly funded by the European Union’s Internal Security Fund — Police (Proposal Number: 820838). This DNAxs version is freely available after signing a license agreement that states that you will not distribute the software to others. To ensure a professional support and capacity for future development of the DNAxs software by NFI, they will charge a yearly fee for any support needed for the use of the software and to have access to new versions of the software. Please note that due to the legal status of the NFI, these services and new versions of the DNAxs software can only be offered to non-profit organisations.
