Hi all,

I'm trying to plot Free Energy Landscapes from Gromacs after using the gmx sham function.

After using the command:

gmx sham -f PCAplot2d.xvg -notime -ls gibbs1-2.xpm

(where PCAplot2d.xvg is the PCA plot generated with the gmx anaeig command)

I get the matrix file in a 2D plot, which can be improved by transforming it into an *eps file, using the command:

gmx xpm2ps -f gibbs1-2.xpm -o plot.eps -rainbow blue

However, I'd like to get the 3D plots for this too, and the Gromacs manual doesn't seem to say anything about this? Any ideas would be greatly appreciated.
