A Method to Detect Differential Gene Expression in Cross Species Hybridization Experiments at gene and probe level

Results: Results: We proposed a novel masking procedure based on currently available target species sequences to filter out probes and studied a cross-species data set using this masking procedure and gene-set analysis. Gene-set analysis evaluates the association of some priori defined gene groups with a phenotype of interest. Two methods, Gene Set Enrichment Analysis (GSEA) and Test of Test Statistics
