Introduction

DNAMIX is a computer program to calcluate likelihood ratios as they pertain to mixed DNA samples encountered in forensic science. The latest version incorporates population structure into the calculations (see DNAMIX v. 2 below). If you have any problems downloading the program or if you have questions about the program, then please contact me.

DISCLAIMER: I assume no responsibility for mistakes in the program or caused by the program. Use DNAMIX at your own risk.

DNAMIX v. 2

DNAMIX v. 2 is based on formulas and methods derived in the paper:

Curran JM, Triggs CM, Buckleton J, Weir BS. 1999. Interpreting DNA mixtures in structured populations. Journal of Forensic Sciences, 44: 937-995.

DNAMIX v. 2 is written in FORTRAN 90; if you have a FORTRAN 90 compiler, then you may want to download the source file dnamix2.f and compile it yourself. The executable file is available for Unix and Windows. A user manual is also available.

Download:

Windows:
dnamix2.f (source code file)
dnamix2.exe (executable file)

Linux/Unix/Macintosh:
dnamix2.f (source code file)

The manual:
Manual in PDF format

DNAMIX v. 1

DNAMIX v. 1 is written in both FORTRAN 77 and C. If you have a compiler for either language, then you may want to download the source code and compile it yourself. Currently, the executable file is only available for PC's. DNAMIX v. 1 is based on formulas derived in the paper:

Weir BS, Triggs CM, Starling L, Stowell LI, Walsh KAJ, Buckleton J. 1997. Interpreting DNA Mixtures. Journal of Forensic Sciences, 42: 213-222.

Download:

dnamix.c (source code for C version)
dnamix.f (source code for FORTRAN 77 version)
example.txt (shows an example run of the program)
readme.txt (gives directions on how to use the program)
DNAMIX.EXE (the executable file for Windows)

Please be sure to obtain the files example.txt and readme.txt as they explain how to use the program.
