GENECAP: a program for analysis of multilocus genotype data for non-invasive sampling and capture-recapture population estimation

We created GENECAP to facilitate analysis of multilocus genotype data for use in non-invasive DNA sampling and genetic capture-recapture studies. GENECAP is a Microsoft EXCEL macro that uses multilocus genetic data to match samples with identical genotypes, calculate frequency of alleles, identify sample genotypes that differ by one and two alleles, calculate probabilities of identity, and match probabilities for matching samples. GENECAP allows the user to include background data and samples with missing genotypes for multiple loci. Capture histories for each user-defined sampling period are output in formats consistent with commonly employed population estimation programs.
