Getting an app

The get_app() function is a top-level import. It allows you to create an app instance by passing the name of the app you want as a string along with the values for any positional or keyword arguments. (See Getting help on an app.) Below, I create an omit_degenerates app for a DNA moltype.

from cogent3 import get_app

just_nucs = get_app("omit_degenerates", moltype="dna")
just_nucs

omit_degenerates(moltype='dna', gap_is_degen=True, motif_length=1)
