How to save cluster assignments in output file using Weka clustering XMeans?

Context

I want to use Weka clustering algorithm XMeans. However I cannot figure out how to obtain cluster assignments from GUI of Weka.

At the moment I can only see a list of cluster IDs along with percentage of entries assigned to each cluster.

Question

There any way to save cluster assignments for each entry in, e.g. CSV format?

Do everything in the "Preprocess Panel".

This is one way to do this:

• Load Data File.

• Remove any Classification Attribute or Identifiers

• Choose Preprocess / Filter / Unsupervised attribute Filter / AddCLuster

• Click on the Word "AddCluster", choose the XMeans Clusterer, click Apply.

• This sghould add a new column "cluster" in the Attribute Panel

• Click on "Save..." Button to export.
