LRR for Granta-519 Cell Line data (published in DeLeeuw et al. (2004). Comprehensive whole genome array CGH profiling of mantle cell lymphoma model genomes, Human Molecular Genetics, 13(17):1827-1837).
Vega-package
(Package: Vega) :
An R package for copy number data segmentation
Vega (Variational Estimator for Genomic Aberrations) is an algorithm that adapts a very popular variational model (Mumford and Shah) used in image segmentation so that chromosomal aberrant regions can be efficiently detected.
plotSegmentation
(Package: Vega) :
Plot observations and the respective segmentation.
This function allows to plot the observed data superimposing the respective segmentation. By the parameter 'opt' he user can plot the LRR mean values of each segment or the computed aberration kind. In plot window the gain and the loss are identified by a line having value of 1 and -1 respectively.
vega
(Package: Vega) :
This function computes, saves and returns the copy number segmentation on the aCGH data passed as argument.
This function computes the segmentation of the copy number data passed as argument. 'vega' function returns the computed segmentation and save it as a tab delimited file. Users need just to use this function.
