• 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 anddrag it over the whole structure in the graphical display.
• Tools/Analysis/Ramachandran Plot Export

A postscript viewer needs to be downloaded onto your machine in order to view the plot. This can be downloaded from http://www.cs.wisc.edu/~ghost/. Once this software is downloaded you need to tell ICM where it is located by typing the pathname into File/Preferences.

NOTE: You can always export the plot as an image directly in ICM without exporting. You can do this by right clicking on the plot and select save as image. Another approach could be to export the RAMA table to Excel and use the plotting tools there. You can do this by right clicking on the table name tab and selecting "Export to Excel" or save as ".csv".
