TRN: Terrain Maps

Parameter Information


Sample Selection (genes/experiments)

The sample selection option indicates whether to perform the analysis on genes or experiments.

Neighbors

Each element is first mapped to an x-y coordinate on the map based on it's similarity to a group of its most closely related neighbors. The mapping to the x-y coordinate system is based on degree of similarity. (The method is described in some detail in the reference for TRN.) The entered number determines the number of nearest neighbors that will influence an element's position in the x-y grid.

The z dimension represents the density of elements within a given area.
