MDM: A Program to Compute Fully Informative Genotype Frequencies in Complex Breeding Schemes

A general algorithm to compute multilocus genotype frequencies under various mating systems

This paper provides a general method to derive algebraic expressions of genotype frequencies for multiple loci under various mating systems, including random mating, back-crossing, selfing, and full-sib mating. For each mating system, general equations are presented. In the case of three loci, comprehensive tables provide recurrence equations for genotype frequencies under random or self mating...

A Program to Compute Gödel-Löb Fixpoints

Briefly, the purpose of this paper is to describe a Prolog program that computes fixpoints in Gödel-Löb computability logic (GL). In order to make things relatively self-contained, I sketch the essential ideas of GL, and discuss the significance of its fixpoint theorem. Then I give the algorithm embodied in the program in a little more detail. It should be emphasized that nothing new is present...

Allele Frequencies and Genotype Frequencies

A computer program to simulate multilocus genotype data with spatially autocorrelated allele frequencies.

Many models for inference of population genetic parameters are based on the assumption that the data set at hand consists of groups displaying within-group Hardy-Weinberg equilibrium at individual loci and linkage equilibrium between loci. This assumption is commonly violated by the presence of within-group spatial structure arising from nonrandom mating of individuals due to isolation by dista...

A complex way to compute fMRI activation.

In functional magnetic resonance imaging, voxel time courses after Fourier or non-Fourier "image reconstruction" are complex valued as a result of phase imperfections due to magnetic field inhomogeneities. Nearly all fMRI studies derive functional "activation" based on magnitude voxel time courses [Bandettini, P., Jesmanowicz, A., Wong, E., Hyde, J.S., 1993. Processing strategies for time-cours...
