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,

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/dnamix2.f and compile it yourself. The executable file is available for Unix and Windows. A user manual is also available.

Windows

• DNAMIX2/dnamix2_windows.f (source code file)
• DNAMIX2/dnamix2.exe (executable file)

Linux

• DNAMIX2/dnamix2_unix.f (source code file)

Manual

• DNAMIX2/manual.pdf

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.

Relevant files

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

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