Table 2 Distance matching

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

Step 1

For all genes, calculate their midpoints (average of start and end base pair position). Do the same for the features on DNA copy number array.

Step 2

For each gene, calculate the distance between its midpoint and that of the DNA copy number array features (mapping to the same chromosome as the gene). See Figure 2.

Step 3

Assign to each gene the DNA copy number data of the feature with minimum distance between its midpoint and that of the gene.
