Composite frequency ideogram plot of genome-wide copy number alterations in 106 diagnostic FL cases based on intersection analysis. (A) The frequencies of aberrations, represented by green signals for losses and red signals for gains, in the autosomes were derived from intersection analysis, where the union was taken between calls made visually by a cytogenetic pathologist and those determined by CNA-HMMer version 0.1. (B) Composite frequency ideogram plot showing only those aberrations affecting at least 10% of cases. The data were visualized using the SeeGH software. Genetic losses or gains are represented by green and red signals, respectively. The horizontal bar below each ideogram represents gain and loss frequencies of +0.25 and −0.25, respectively.
