Figure 3From: HHT diagnosis by Mid-infrared spectroscopy and artificial neural network analysisRelevant wavenumbers/features used for ANN analysis of HHT patient and control group spectra. For each wave number the Bhattacharyya coefficient was calculated. A wavenumber was selected if Bhattacharyya coefficient was greater than 5% of the greatest coefficient. The selected wavenumber regions are marked by the black lined peaks and open rectangles.Back to article page
