From: Relating the shape of protein binding sites to binding affinity profiles: is there an association?
Superimposed Scree plots based on the MAF fingerprints and the PocketPicker descriptors. Cumulative variance explained by the PCA factors for the geometric descriptor matrix based on PocketPicker (red circle) saturates much faster than the cumulative variance for the MAF profiles (black square), suggesting that the MAF matrix has more complex structure. The first 40 factors of both matrices are plotted.
