calculateTangentNormal {PureCN} | R Documentation

## Calculate tangent normal

### Description

Reimplementation of GATK4 denoising. Please cite the relevant GATK publication if you use this in a publication.

### Usage

    calculateTangentNormal(tumor.coverage.file, normalDB, num.eigen = 20,
      ignore.sex = FALSE, sex = NULL)

### Arguments

`tumor.coverage.file` | Coverage file or data of a tumor sample.
`normalDB` | Database of normal samples, created with `createNormalDatabase`.
`num.eigen` | Number of eigen vectors used.
`ignore.sex` | If `FALSE`, detects sex of sample and returns best normals with matching sex.
`sex` | Sex of sample. If `NULL`, determine with `getSexFromCoverage` and default parameters. Valid values are `F` for female, `M` for male. If all chromosomes are diploid, specify `diploid`.
