Example Commands
================

First we create the reduced lexicon table with: 

.. code-block:: bash

	dlatkInterface.py -d dla_tutorial -t msgs -c user_id -f 'feat$cat_met_a30_2000_cp_w$msgs$user_id$16to16' --fit_reducer --model nmf --reducer_to_lexicon msgs_reduced10_nmf --n_components 10

Then we can refer to the above table during downstream analysis:

.. code-block:: bash

	dlatkInterface.py -d dla_tutorial -t msgs -c user_id  --reduced_lexicon msgs_reduced10_nmf --super_topics msgs_10nmf_fbcp -l met_a30_2000_cp
