hi: I find the question in the past posts ,bu i do not find the answer.

I am new user to the modeler, I have started with the basic tutorial, I have difficulty with plotting the dope scores with GNU plot, when I plot the two dat files '1bdma_dope.dat','TVLDH_dope.dat'(from the tutorials folder) I get the graph plotted(Dope score vs Residue Index), but the two graphs are not aligned, as shown in the tutorial html file. how to align the graphs. hope someone could help me with this silly doubt.

Thank you very much.
