and Rarefaction Analysis Tool (RE-RAT)
Relatedness Estimation and Rarefaction Analysis
(RE-RAT) is a web-based tool for calculation of microsatellite-based
pairwise relatedness estimates and for the execution of rarefaction analyses
to determine the number of loci needed to provide stable estimates of relatedness.
was originally developed by Lori
Schwacke and Patricia
Rosel of the National Oceanic and Atmospheric Administration (NOAA)
as a tool for performing rarefaction analyses and testing relatedness hypotheses
for populations of small cetaceans. A web-based interface has now been
added so that RE-RAT is easily accessible from a variety of platforms and
is being made freely available to the scientific community.
RE-RAT offers 4 functions:
Both Queller and Goodnight (QG) and Lynch and Ritland (LR) estimators are
available for relatedness calculations. For QG estimates, both symmetric
and asymmetric relatedness matrices are available.
