Structural variability of the three statistical word types of W set
. a) Intra-word structural variability: distribution of the RMSd
. The vertical line corresponds to a threshold of 0.6 Å b) Inter-word structural variability: Sammon's map computed from the RMSd
for a sample of 890 words of W set≥30. All the points are subjected to the same projection and plotted on distinct plots.
