[gmx-users] pca

[pratibha kapoor]

Dear all gmx-users

I have done pca at three different temperatures and  would like to draw
combined 2D free energy landscape (pc1 versus pc2) and 3D free energy
landscape (pc1, pc2, and energy).
I have used g_sham and created three different 2D plots. My question is how
to combine these three plots in order to get all information from three
temperatures in one plot? Also please guide me in creation of 3D plots.

Thanks.
