Genetic networks in Parkinson’s and Alzheimer’s disease

Figure 2.Scale free network topology (signed R^{2}) for different soft-thresholding powers of data. A soft thresholding power that achieved a scale-free topology of R^{2} of 0.85 was chosen to define approximate scale-free topology. We found that the (A) ADHC data achieved approximate scale-free topology at a soft thresholding power of 6 and the (B) ADMCI and (C) ADAD data at a soft thresholding power of 4. The (D) PDHC data reached approximate scale-free topology at a soft thresholding power of 10 and (E) PDPD data at a soft thresholding power of 13.
