Neighborhood Analysis

Neighborhood analysis is very simple and pretty powerful.
The neighborhood index is defined as the number of genes that lie within the query gene’s R
nearest expression neighbors. For a given query, G, all genes represented in the expression set are first ordered according to the Euclidean distance (or other appropriate distance) of their normalized expression pattern across all experimental conditions.
