Multiplex Amplicons for Drug, Diagnostic, Diversity, and Differentiation HAplotypes via TargeTed Resequencing (MAD4HatTeR)

An Illumina-compatible, modular, highly multiplexed amplicon sequencing panel P falciparum with a broad range of targets and the ability to genotype low density, polyclonal field samples. Two modules:

1) a diversity panel with 165 highly diverse microhaplotypes

2) 118 targets that cover drug and diagnostic resistance genes as well as non-falciparum species identification and vaccine candidates.

dcifer- Distance for Complex Infections: Fast Estimation of Relatedness

An IBD-based method to calculate genetic distance between polyclonal infections by estimating relatedness from biallelic and multiallelic data. In addition to estimates, the package provides a likelihood function and statistical inference. Functions for reading and reformatting data, performing preparatory steps, and visualizing the results are also included.

THE REAL McCOIL, - Turning HEterozygous SNP data into Robust Estimates of ALelle frequency, via Markov chain Monte Carlo, & Complexity Of Infection using Likelihood

A Markov chain Monte Carlo method that estimates complexity of infection and population allele frequencies using SNP data obtained from Sequenom or similar types of SNP assays.     We used the data in two ways:

categorical- where we consider SNP to be heterozygous or homozygous
proportional- where relative signal intensity for each allele is used

MicroSPAT- MicroSatellite Parameterized Analysis Tools

A collection of tools for semi-automated analysis of raw capillary electrophoresis (CE) data output by the ABI 3730, and has been designed specifically for working with multi-allelic samples. Developed to improve reproducibility and consistency of microsatellite analysis between analysts.
