Principal component analysis. (a–c) Two-dimensional PC plot trajectory projection on the essential subspace for chains 1 through 3 for Unlig, Gin, and C14 are colored in green, orange, and violet for chains 1, 2 and 3, respectively. (d–f) Two-dimensional PC plot trajectory projection for chains 4 through 6 for Unlig, Gin, and C14 are colored in green, orange, and violet for chains 4, 5, and 6, respectively.
