Visualization of the array-based CGH results by VAMP. (A) Overall frequency of CNAs in MF patient tumor biopsies, calculated using the FrAGL (frequency of amplifications, gains, and losses) option of VAMP. Losses are represented on the negative scale as green bars; gains are presented on the positive scale as red bars. (B) Averaged CGH pattern of all 22 MF tumor samples. MCRs with loss occurring in at least 35% of patients are indicated as green vertical lines, and MCRs with gain as red vertical lines. All data are presented ordered by chromosomal map position of the clones, excluding sex chromosomes.
