We have to begin our work by loading the library:

library(CNVScope)

Following this, we’ll obtain TARGET low-pass neuroblastoma data (NBL) from the GDC archive. Please note: TARGET_NBL_WGS_CNVLOH.tsv is a clinical metadata file and therefore not compatible with the ensuing functions to extract segment data. We have also chosen to use only a single comparison type (NormalVsPrimary) to ensure comparability and compatibility with the data. Users can download the tar.gz file and remove the tsv files into a single folder. We have already done that here. The source for these files is located here The user simply chooses to add all the files to the cart, then click the black cart button in the top right hand corner.
