Abstract
The software DetSex implements a Bayesian model-based classifier to assign markers to their chromosome type (autosomal, sex chromosome, mitochondrial or chloroplastic) and/or to infer the sex of individuals from genotyping data. The DetSex model accounts (and estimates) for the allele frequencies in the population(s) and the genotyping error rate for each marker. DetSex is written in Fortran90. The executables for various platforms (currently Windows and Linux) are available and the source code will be made available upon acceptance of the paper describing the method. The manual provides information about how to format the data file, how to specify the user-defined parameters, and how to interpret the results.
