- description: Schemes for subsampling data prior to phylogenetic inference to avoid sampling bias or focus an analysis on specific spatial and/or temporal scales. `See the SARS-CoV-2 tutorial for more details on defining subsampling schemes <https://docs.nextstrain.org/projects/ncov/en/latest/analysis/customizing-analysis.html#subsampling>`__.
+Predefined subsampling schemes are:
+
+- ``all``
+- ``region``
+- ``region_global``
+- ``region_grouped_by_country``
+- ``country``
+- ``division``
+- ``location``
+
+See `defaults/parameters.yaml <https://github.com/nextstrain/ncov/blob/master/defaults/parameters.yaml>`__ for definitions.
+
Each named subsampling scheme supports the following attributes that the workflow passes to ``augur filter``.
