how to throw the last module's parameters to the next module's parameters

Hey Joe,

the Clone Parameters operator only works for identical operators (e.g. copy the parameters of one K-Means operator to another K-Means operator). Anyway, you are using k-Medoids which does NOT create a hierarchical clustering, and thus you don't need the Flatten Clustering operator at all. You can also see in your process setup that something is wrong by the red input port at the operator and by looking at Problems View below.

Anyway, to use the same parameter value at several places in your process, you can use macros. They work like gloal process variables. Set them via the Set Macro operator. Say you create a macro named number_of_clusters and value 5. Then you can use it as k in k-Medoids by entering the following into the k-parameter field in k-Medoids:

%{number_of_clusters}

Kind regards,
Marius
