KinBN

KinBN is a free software (GNU General Public License v3.0) for kinship analysis based on the Bayesian network . It can be applied to short tandem repeat (STR) markers commonly used in forensic genetics to calculate the likelihood ratio (LR) considering the linkage between loci, mutation, and drop-out. The software is a graphical user interface written in R language. The software has been validated under various conditions.

Changes in v2.1.0

Added functionalities:

• The software can be used as the R-package KinBN.

• The software can calculate the LR value while accounting for allele drop-out.

• Project data can be saved and loaded as required.

Minor changes:

• Conditional probabilities of mutation rates were corrected.

• Layout of the software has changed.

• The user can set the calculation conditions, such as the estimation method of allele frequency, in the Setting tab.
