 ## Complexity Filtering Options
 
-### `--complexity_filter`
+### `--complexity_filter_poly_g`
 
 Performs a poly-G tail removal step in the beginning of the pipeline, if turned on. This can be useful for trimming ploy-G tails from short-fragments sequenced on two-colour Illumina chemistry such as NextSeqs (where no-fluorescence is read as a G on two-colour chemistry), which can inflate reported GC content values.
