Figure 5From: Identifying technical aliases in SELDI mass spectra of complex mixtures of proteinsNumber of technical clusters and clustered peaks from fractionated plasma dataset as a function of algorithm variance threshold. The Technical Clustering software was applied to a dataset of 1350 peaks from 85 fractionated samples processed in duplicate in a biomarker discovery dataset at the indicated Threshold CV. A) Number of technical clusters using the original table of peaks (closed red circles); peaks randomized within groups simulated data (closed blue squares); and peaks fully randomized simulated data (closed green triangles); B) The number of peaks within technical clusters for the original data (open red circles); simulated data using peaks randomized by sample within groups (open blue squares); and simulated data using peaks fully randomized by sample (open green triangles).Back to article page
