Dear Dr. Lemkul I did it. It works. Thank you very much for the advise. Now I am having issues opening the (.xpm) files generated that contain for example the gibbs energy landscape on the two first eigenvectors of the dPCA.
If I use the command "gmx xpm2ps -f gibbs-1_2.xpm -w yes -o gibbs-1_2.eps" it write this error: "Input error or input inconsistency: Invalid XPixMap" Do you know if I am missing something here? Do I have to install something in my OS to be able to see .xpm images?
