Description

ichorCNA is an R package for calculating copy number alteration from (low-pass) whole genome sequencing, particularly for use in cell-free DNA. This module generates a panel of normals

Input

Name (Type)
Description
Pattern

wigs (file)

Any number of hmmcopy/readCounter processed .wig files giving the number of reads in the sample, in each genomic window. These will be averaged over to generate the panel of normals.

*.{wig}

gc_wig (file)

hmmcopy/gcCounter processed .wig file giving the gc content in the reference fasta, in each genomic window

*.{wig}

map_wig (file)

hmmcopy/mapCounter processed .wig file giving the mapability in the reference fasta, in each genomic window

*.{wig}

centromere (file)

Text file giving centromere locations of each genome, to exclude these windows

*.{txt}
