HELP: Is "Resample" my best bet to solve this problem?

In the attached file, you will find two wave pairs:

Mid_v_Y_ILM is plotted against Mid_v_X_ILM

and

Mid_v_Y_BM is plotted against Mid_v_X_BM

Now, I need to subtract one wave from the other. Because they have different X axis, I can not do that. Is "Resampling" the two wave pairs my best bet?

The file is attached. Thanks A lot! resample.pxp
With that small number of data points, perhaps using the Interpolate XOP (Analysis->Interpolate) on each XY pair and then subtracting from the interpolated waveforms is the way to go.

Thank you, Jim. It worked.
