PCAE.gp contains the energy landscape:
	First column: PC1 (x-value)
	Second column: PC2 (y-value)
	Third column: energy (z-value, i.e. color)
	Has been plotted with an energy cut-off of 6
PCA.min contains the coordinates of the minima:
	Sixth column: PC1 (x-value)
	Seventh column: PC2 (y-value)
	Last column: energy (have only plotted those less of equal to 3)
