To make an interactive ramachandran plot:

• Read in a protein structure (File/Open or PDB Search)
• Select the structure you wish to build the plot for. You can do this by double clicking on the name of the structure in the ICM Workspace (a selection is highlighted blue in the ICM Workspace and green crosses in the graphical display) or you can use the right-click button and drag it over the whole structure in the graphical display.
• Tools/Analysis/Ramachandran Plot Interactive
• The interactive ramachandran plot will be displayed in table called RAMA.
• You can view the Omega, Phi/Psi (Gly) or Phi/Psi angles by clicking on the tabs at the top of the plot. Each point is linked to the data in the table RAMA and also to the graphical display. Soby clickin on a point in the plot will highlight the corresponding angles in the table and also center on this region in the 3D display.
