Additional summary measured for the segments

Description

This program computes the frequency of gains and losses for each probe as a function of level of mad.

Usage

  glFrequency(xout, threshold=1)

Arguments

Value

A segment is called a gain or loss if the segment mean is at least the threshold* mad distance away from the median copy number level. The output is a data frame with five columns which give the chromosome (chrom), genomic position (maploc), the number of samples with available data (pfreq), and the gain (gain) and loss (loss).
