The next step was to use those crosscorrelations to predict one trace from the other. At places where two traces are similar to each other, the prediction error is small. At places where two traces are dissimilar, the prediction error is large. The dissimilarity attribute chosen for this task originally was the mean-square prediction error, which is a positive quantity. Thus, low points on the dissimilarity attribute curve represent points of weak discontinuity between two traces, and high points on the dissimilarity attribute curve represent points of strong discontinuity between two traces. This was an early use of seismic attributes. Ideally, this attribute would stick out like the proverbial sore thumb at the location of reflections.
