Introduction

apt-copynumber-log2ratio is a component of the CN5 suite of applications for finding de novo copy number changes and Loss of Heterozygosity (LOH) on a per sample basis with respect to a reference set of samples. The copy number algorithm it implements assumes that the reference set comprises a mix of normal human males (with XY chromosomes) and normal human females (with XX chromosomes). The algorithms assume that in this reference for each autosomal marker (SNP or Copy Number probe) the predominant Copy Number is 2, and for the sex chromosomes the copy number is determined by the gender.

apt-copynumber-log2ratio implements the portion of the workflow that generates log2ratio and allelic difference values for each probe set.

Most users will probably want to use apt-copynumber-workflow which provides a complete copynumber analysis from CEL files to CNCHP files.

Quick Start

The basic requirements for a run of apt-copynumber-log2ratio are:

On unix systems a basic command using the default parameters to do a batch run on GenomeWide SNP 6.0 data would look like:

apt-copynumber-log2ratio \
    --set-analysis-name Test \
    --log2-input false \
    --hdf5-output true \
    --text-output false \
    --cnchp-output false \
    --call-copynumber false \
    --netaffx-snp-annotation-file lib_directory_name/GenomeWideSNP_6.na25.annot.csv \
