I loaded my hyperspectral image (Hyperion EO1) and performed all the preprocessing steps but when I used the countEndmembersHFC method to calculate the number of endmembers, I encountered this error:

is hcube a 3d numeric array? Or is it a hypercube() object with 3d real non-sparse data?

For better estimation of number of endmembers, countEndmembersHFC validates the input data along spatial and spectral dimensions. It expects the input data to be having unique channels/ bands with non - homogenous data. Looks like the data you are passing to countEndmembersHFC is having homogenous data along spatial or spectral dimensions.

Workaround is to make sure that the input data that you are passing to countEndmembersHFC should have unique channels and non-homogenous data.
