Figure 3From: Widespread, focal copy number variations (CNV) and whole chromosome aneuploidies in Trypanosoma cruzi strains revealed by array comparative genomic hybridizationChromosomes were typed based on CNV signatures. Diagnostic CNV were selected based on the criteria that they were at least 500 bp in length, represented by at least 5 oligonucleotide probes, and had log2ratios of at least +/- 1 (tolerance of 0.2) in at least 5 strains. Up to two CNV meeting the criteria were selected for each chromosome based on their ability to differentiate between the strains; i.e. the CNV that separated the strains into the highest number of groups compared to other candidate diagnostic CNV were selected. Thus, for each chromosome there were a finite number of signature types to which strains were assigned based upon the presence/absence of the diagnostic CNV's the direction of change (log2ratio +/- 0.8). Each chromosome type is represented by a different color, with CL-Brener always assigned to type 'A' (blue). The strains were then sorted based on the overall similarity of their chromosome types, taken together, relative to CL-Brener.Back to article page
