There are currently two main functions of PRIMUS. The first is an algorithm to reconstruct pedigrees within a genetic dataset. PRIMUS can verify expected pedigree structures from genetic data, and it can identify and incorporate novel, cryptic relationships into pedigrees. The second function of PRIMUS is an algorithm adapted from graph theory that identifies the maximum set of unrelated individuals in any dataset, and allows weighting parameters to be utilized in unrelated sample selection.

PRIMUS is free for academic or non-commercial use, please register on the PRIMUS website for non-commercial access:
