p("Constructing a weighted gene network entails the choice of the soft thresholding power β to which co-expression
similarity is raised to calculate adjacency. The authors (B. Zhang and S. Horvath, 2005) have proposed to choose the soft thresholding
power based on the criterion of approximate scale-free topology. We refer the reader to that work for more details;
here we illustrate the use of the function pickSoftThreshold that performs the analysis of network topology and aids
the user in choosing a proper soft-thresholding power. The user chooses a set of candidate powers (the function provides
suitable default values), and the function returns a set of network indices that should be inspected, We choose the power
which is the lowest power for which the scale-free topology fit index curve flattens out upon reaching a high value.")

# p("SSDA can elucidate samples distance in the high-dimensional space. In RNA-seq data, each gene is a dimension,
# so the data has tens of thousands of dimensions. SSDA uses Euclidean distance to elucidate samples distance in the
# high-dimensional space, which helps to understand the relationship of samples across exprimental conditions or sample replicates.
# The heatmap clusters samples with similar distances, which makes the results easier to interpret.")
