Following recent reports we can confirm that when using the Naive Bayes clustering alternative to the RNL clustering, the standard deviations instead of the means were used for downstream colour pattern analysis. This bug concerns all realeses of the toolbox incl. v2.3. This has now been fixed and should appear in the next toolbox update. If you are in urgent need of an updated version prior to this, please contact the developers.
