Table 4 Overlap matching

From: Matching of array CGH and gene expression microarray features for the purpose of integrative genomic analyses

Step 1

For each gene, calculate the percentage of overlap between its sequence and that of the DNA copy number array features (mapping to the same chromosome as the gene). The percentage of overlap is defined as the number of overlapping base pairs between the two sequences divided by the length of the DNA copy number probe.

Step 2

Assign to each gene the DNA copy number data of the feature with the maximum percentage of overlap between its sequence and that of the gene.
