DSPR Genotypes (B population)

This file contains genotypes for the population B RILs (Recombination Inbred Lines) of the DSPR (Drosophila Synthetic Population Resource). The genotypes were originally published in King et al. (Genome Research 2012, 22:1558-66) and are also available at www.FlyRILs.org (Data Release 2 - HMM Results for pB RILs at regularly spaced 10 kb intervals). The genotypes are derived from a Hidden Markov Model (HMM) at regularly spaced 10KB positions along the Drosophila melanogaster genome. There are no column headers in the file. Columns are: chromosome, genome position, line identifier, 36 columns of founder genotype probabilities, and 8 columns of additive probabilities. The precise names for each of the columns are listed in the analysis R code file for population B. Together with this code, and the nicotine resistance phenotype scores, a user can recapitulate the QTL mapping from Marriage et al
