Hi, Please ignore my previous incomplete mail. It seems that you have got PC1, PC2 and Gibb's free energy in the x, y and z axes respectively. If I am not wrong you first combined the pc1.xvg and pc2.xvg to a single .xvg file compatible with gmx sham. Right? Then, You must have converted the

Dear all I have plotted the Free Energy Landscapes(2D) of proteins from First two principal components as used by GROMACS, But after that I am confused how to do clustering on PCA surface or I want to know how to calculate the structure of protein corresponding to lowest free energy in FELs. Is
