**Command Documentation**

The sub.sample_ command can be used as a way to normalize your data, or to create a smaller set from your original set. It takes as an input the following file types: fasta, list_, shared_, rabund_ and sabund_ to generate a new file that contains a sampling of your original file.

.. _list: https://www.mothur.org/wiki/List_file
.. _shared: https://www.mothur.org/wiki/Shared_file
.. _rabund: https://www.mothur.org/wiki/Rabund_file
.. _sabund: https://www.mothur.org/wiki/Sabund_file
.. _sub.sample: https://www.mothur.org/wiki/Sub.sample
