Common questions
What distinguishes EuroForMix from earlier binary mixture interpretation methods?+
It uses a continuous model that incorporates peak height information and stutter directly into the statistical calculation, rather than treating each allele as simply present or absent, which generally yields more informative likelihood ratios from complex or low-template mixtures.
Why does being open source matter for a probabilistic genotyping tool used in court?+
An open-source R package lets independent experts and defense analysts inspect the underlying statistical model and code, supporting the transparency and validation that courts increasingly expect before accepting probabilistic genotyping results.
Is EuroForMix used only by European forensic laboratories?+
It was developed in Norway and is used by several European national institutes, but as an open-source tool it is technically accessible to any laboratory worldwide that chooses to validate and adopt it, not restricted to European agencies.
