Dotplot with annotated sequences#

If sequences in a dotplot have been annotated, the dotplot() method returns an AnnotatedDrawable.

Reloading from json#

The data file, tp53.json, was created from a query of ensembl for one-to-one orthologs of human TP53 between Human, Macaque, Orangutan and Marmoset. The resulting sequences were annotated with the location of the CDS for the canonical transcript, then the SequenceCollection was saved as json using write_json.

from cogent3 import get_app

loader = get_app("load_json")
seqs = loader("data/tp53.json")
dp = seqs.dotplot(name1="Macaque", name2="Marmoset", width=600)
dp.show()

Removing annotation tracks#

help(dp.remove_track)
Help on method remove_track in module cogent3.draw.drawable:

remove_track(left_track=False, bottom_track=False) method of cogent3.draw.drawable.AnnotatedDrawable instance
    Parameters
    ----------
    left_track : bool
        the left track is removed
    bottom_track : bool
        the bottom track is removed

Thus we could remove the left annotation track, for instance with

dp.remove_track(left_track=True)
dp.show()
