MMDIT
is a tool for the deconvolution and interpretation of mitochondrial DNA mixtures (whole or partial genomes). The application has an interactive graphical user interface and open source code available on GitHub. This software allows users to deconvolve mixtures into constituent donor haplotypes and estimate random match probabilities on the resultant haplotypes. In cases where deconvolution might not be feasible, the tool allows mixture analysis within a binary framework.

OSIRIS
is free, public domain, open source DNA analysis and quality control software that is developed by NCBI at NLM/NIH for STR profile analysis and fragment analysis. Windows and Macintosh versions are available on the OSIRIS homepage, and the source code is available on GitHub. The most recent version of OSIRIS features fragment analysis, which enhances its use for research and home-made marker sets for which there is no allelic ladder. It also features an improved export to facilitate formatting data for export to mixture analysis software. OSIRIS has been validated, and accepted by the FBI, as an expert system for the US National DNA Database (CODIS). OSIRIS is in use in government laboratories for forensic casework, convicted offender testing, and clinical testing for stem cell engraftment.

DNAxs 2.0
is a user-friendly, well-validated software that compares profiles within seconds and proceeds to statistical analysis according to advanced probabilistic models will increase the quality and number of cases that can be handled, and stimulate the use of such advanced statistics. It has been developed by the Netherlands Forensic Institute (NFI) and can be obtained from the NFI upon inquiry:

LRmix Studio
is an open-source, free of charge software dedicated to the interpretation of complex forensic DNA profiles. As a result of the development of
DNAxs
, no further development is performed on the semi-continuous model LRmix Studio, with the exception of bug fixes. LRmix Studio is no longer available from lrmixstudio.org, but has been migrated to GitHub, from which the software can be downloaded:
https://github.com/smartrank/lrmixstudio/releases
LRmix Studio is the successor to LRmix. Both programs implement the same model, however LRmix Studio is a more flexible, faster version of LRmix. It can be run on all platforms, and requires Java version 7 or higher.
The
forensim package
for the open source
R statistical software
is dedicated to forensic DNA mixtures interpretation. It provides tools to simulate mixture cases, and analytical tools to interpret data. The codes have been developed by Hinda Haned (Lyon).

DNAmixtures
(
http://dnamixtures.r-forge.r-project.org
) is a statistical software for analysing DNA samples from one or multiple donors. It is developed by Therese Graversen and is based on the
"fully continuous" statistical model
for peak heights described in
Analysis of forensic DNA mixtures with artefacts. RG Cowell, T Graversen, S Lauritzen, and J Mortera. Journal of the Royal Statistical Society, series C. Volume 64, Issue 1, 1-48, 2015.
