Dear All,

I add multiple layers (up to 15) with the same resolution and projection. Some of them are RGB bands, other indices (es. NDVI), other PCA values from ArcGIS (since I cannot conclude PCA in eCognition, already opened doscussion). I perform a segmentation, then I classify and create some samples, then I apply a supervised classification object based but the feature selected for the analysis are not supported. The mean works only with the indices and RGB values, not for PCA layers, moreover, if I also choose standard deviation or texture features it returns the same error attached. I wonder if I will manage somehow to conclude the train and applying of the classification.

Many thanks,

Stefano
