## Impute the Sanger SNPs onto DO genomes

### Description

Given a set of DO genotype probability files and the location of the Tabix indexed Sanger file, impute the Sanger SNPs on to DO genomes.

### Usage

      do2sanger(do.files, snps, output.file = "do2sanger.txt", snp.file =
      "ftp://ftp.jax.org/SNPtools/variants/cc.snps.NCBI38.txt.gz")

### Arguments

`do.files` | Character vector of *.genotype.probs.Rdata files that contain the posterior probabilities.
`snps` | Data.frame containing the marker locations. SNP ID, chromosome, Mb anc cM locations in columns 1 through 4, respectively.
`output.file` | Character string to write the results to.
`snp.file` | Character string with path to a Tabix indexed SNP file. Default is from JAX FALSETP site

### Details

We read in a single genotype probability file, which must have been saved as a *.Rdata file. The format is a matrix with markers in rows and states in columns and dimnames for both. FALSEor each pair of markers, we take the average genotype probability. Then we take the DO genotype with the highest probability and split it into the two founder haplotypes. We get the Sanger SNPs for each of the two founders, convert them to 1, 1 or 2 and insert them into the DO sample.

### Value

No value is returned. The Sanger SNPs mapped onto the DO genomes are written out to the output.file. The file will contain 0, 1 or 2 as the allele calls.
