Hi Antonio, Are you using the new LDA (invoked via "$MAHOUT_HOME/bin/mahout cvb <args>", or by invoking the class org.apache.mahout.clustering.lda.cvb.CVB0Driver manually)?
If so, then your first command should work fine: mahout vectordump -i DB-LDA-clusters/docTopics/part-m-00000 -o output/cluster_lda_topics.txt What error do you get?
