GEMINI heat map results showing 9 nearest neighbors to the query (top row) for four samples. Four query profiles were used to search for nearest-neighbor profiles in a database containing both ovarian and breast cancer samples. The nearest neighbors of the prototypical breast cancer profile are all breast cancer samples and the nearest neighbors of the prototypical ovarian cancer profile are all ovarian cancer samples as expected. The ovarian cancer sample that falls in the breast cancer cluster is nearest neighbors with both ovarian and breast cancer samples. The ovarian cancer outlier has all breast cancer samples as nearest neighbors indicating that the differential gene expression patterns for that sample most closely resemble breast cancer
