Description

Function to create a database of normal samples, used to find a good match for tumor copy number normalization.

Usage

createNormalDatabase(gatk.normal.files, ...)

Arguments

Value

A normal database that can be used in the findBestNormal function to retrieve good matching normal samples for a given tumor sample.

Examples

gatk.normal.file <- system.file("extdata", "example_normal.txt", 
    package="PureCN")
gatk.normal2.file <- system.file("extdata", "example_normal2.txt", 
    package="PureCN")
gatk.normal.files <- c(gatk.normal.file, gatk.normal2.file)
normalDB <- createNormalDatabase(gatk.normal.files)
