Description

This column shows how similar the GNF expression data for of the gene to data for the selected gene. Genes with identical expression profiles will have a 0 in this column. This column only has data for the 1000 genes (including splicing variants) that have the most similar expression profiles.

Method

The expression distance between two genes is a weighted sum computed with the following formula:
delta(a,b) = sum(w[i] * |a[i] - b[i]| ) / sum(w[i])
where a and b are expression vectors associated with the two genes indexed by tissue, w is an array of weights, and the sums are taken over all tissues. The values for the weights are currently all 1.0.
