+%
+% OUTPUT
+%
+%   rez                   Cleaned rez structure with noisy clusters removed.
+%
+% NOTES
+%
+% - The function modifies the `rez` structure in place, removing identified
+%   noisy clusters and optionally exporting updated cluster labels for phy.
+%
+% - Noise detection is based on several criteria, including Mahalanobis
+%   thresholds, autocorrelograms, waveform characteristics, and user-provided
+%   noise intervals.
+%
+% - If a `savepath` is provided, the function appends noise labels to an
+%   existing `cluster_group.tsv` file or creates a new one if it doesn't exist.
+%
+% EXAMPLES
+%
+%   % Clean rez file with default settings
+%   cleanRez = CleanRez(rez);
+%
+%   % Clean rez file and save noise labels for phy
+%   cleanRez = CleanRez(rez, 'savepath', '/path/to/phy/files');
+%
+%   % Clean rez file with custom Mahalanobis threshold
+%   cleanRez = CleanRez(rez, 'mahalThreshold', 15);
