XRanges {cn.mops} | R Documentation

## A simulated data set for CNV detection from NGS data.

### Description

This data set gives the read counts of 40 samples in 5000 genomic locations. The rows correspond to genomic segments of 25kbp length and the columns to samples. An entry is the number of reads that map to the specific segment of the sample. The "GRanges" object contains the name of the reference sequence, start and end position of the genomic segments. The simulated data contains CNVs given in the `CNVRanges` object. It was generated using distributions of read counts as they appear in real sequencing experiments. CNVs were implanted under the assumption that the expected read count is linear dependent on the copy number (e.g. in a certain genomic we expect lambda reads for copy number 2, then we expect 2*lambda reads for copy number 4).

### Usage

### Format

A GRanges object with 5000 rows and 40 value columns across 1 space.
