Subtract Reference

Generate residues by subtracting a reference signal when you want to focus your analysis on signal variation by removing normal ensemble-level behavior such as the ensemble mean.

To compute residues, you must already have at least one Ensemble Statistics signal the statistical signal that you want to remove. To generate these signals, use Filtering & Averaging > Ensemble Statistics.

• Signal to subtract — Choose from the list of available statistical signals.

The software stores the results of the computation in a new variable. The new variable name includes the source signal name with the suffix res.
