calc.genoprob.intensity {DOQTL} | R Documentation

## Calculate the founder genotype probabilities at each SNP.

### Description

This function performs genome reconstruction using allele intensities. We recommend using allele intensities where available because they often produce better genotype reconstructions.

### Usage

      calc.genoprob.intensity(data, chr, founders, snps, output.dir = ".", trans.prob.fxn,
      plot = FALSE)

### Arguments

`data` | A list with named elements containing the information needed to reconstruct genomes. When method = intensity: x: Numeric matrix, num.samples x num.snps, with X intensities for all samples. Sample IDs and SNP IDs must be in rownames and colnames. y: Numeric matrix, num.samples x num.snps, with Y intensities for all samples. Sample IDs and SNP IDs must be in rownames and colnames. sex: Character vector, containing "M" or "F" indicating sex. Sample IDs must be in names. gen: Character matrix containing the generation of DO outbreeding for each sample. For the DO, this should be "DO" followed by a number with no space between them. For CC mice, this should be CC. Sample IDs must be in names.
`chr` | Character vector containing chromosomes to run. Must match the chromosome IDs in the snps table. "all" (default) will run all chromosomes.
`founders` | List containing founder information for non-DO or CC crosses. Not required for DO. When method = intensity: x: Numeric matrix, num.samples x num.snps, with X intensities for all founders and F1s (if available). Sample IDs and SNP IDs must be in rownames and colnames. y: Numeric matrix, num.samples x num.snps, with Y intensities for all founders and F1s (if available). Sample IDs and SNP IDs must be in rownames and colnames. sex: Character vector, containing "M" or "F" indicating sex. Sample IDs must be in names. code: Character vector containing two letter genotype codes for each founder sample. Sample IDs must be in names.
`snps` | Data.frame containing the marker locations. SNP ID, chromosome, Mb anc cM locations in columns 1 through 4, respectively. Not required for DO.
`output.dir` | Character string containing the full path where output should be written. The directory must exist already.
`trans.prob.fxn` | FALSEunction to call to estimate the transition probabilities between markers for non-DO samples. Not required for DO.
`plot` | Boolean that is true if the user would like to plot a sample chromosome as the model progresses. Default = TRUE.

### Value

No value is returned. The output files are written to output.dir.
