Fig. 4From: G4Boost: a machine learning-based tool for quadruplex identification and stability predictionThe frequency distribution of the selected features to build the prediction model for folded (blue) and unfolded (red) G4s. The features include A CC and B GG dinucleotide contents, C C and D G nucleotide contents, E motif length, F input sequence length, G minimum loop length, H maximum loop length, I the number of G-quartets, and J the number of loopsBack to article page
