DNATYPE for Windows 95/NT: User Manual and Guide

NCJ Number
Date Published
109 pages

This manual explains a collection of computer software called DNATYPE; these computer programs are used for analyzing genetic data and databases for forensic populations.


Most of the programs are written in BASIC; one is written in FORTRAN. They run in DOS windows that pop up when the programs are run. Each program has an alphabetic letter that serves as a shorthand label, except for NRC, which does calculations of probability of a chance duplicate in a population according to the recommendations of the National Research Council report of 1996. The programs can be run in a Windows 95/NT interface to create, edit, and check population database files; perform tests for independence within, between, and among loci in a database; search database files for complete or partial matches; and calculate the probability of a chance match for a user-specified profile following NRC II guidelines. The manual provides information on each program's requirements, the background of the statistical tests it performs, its output, and the interpretation of the results.
