mrc-ide/genescaper: Allele frequency mapping and outlier detection

Inputs data consisting of allele frequencies at sampling sites along with their latitude/longitude values. Fits a model of smoothly varying allele frequencies in space (a Gaussian Random Field) via Bayesian MCMC. Uses the fitted model to predict allele frequencies at any given point in space, and also to generate a null distribution for pairwise genetic distances between sites. This null distribution can then be used to detect outliers, which may represent sites that are more/less connected than we would expect by chance.
