Working with Annotations

COPASI and SBML files can be annotated with MIRIAM annotations. These annotations describe what the model and its constituents actually represent. In basico you can ask for these annotations using the get_miriam_annotation function, simmilarly, you can set them using the set_miriam_annotation commands.

So lets start as usual, loading basico:

import sys
if '../..' not in sys.path:
    sys.path.append('../..')


from basico import *
from ipywidgets import HTML
%matplotlib inline

Resource Lists / Updating

For the resolving of MIRIAM entries to work, occasionally COPASI needs to update the list of MIRIAM resources. This will be necessary on systems, where the graphical user interface to COAPSI has not been installed. To see whether it is necessary, you can call:

have_miriam_resources()

True

Should that call return false, simply update the resources using:

update_miriam_resources()

To see the list of terms currently known by COPASI you can use the function:

get_miriam_resources().head()

	is_citation	uri
resource
2D-PAGE protein	False	http://identifiers.org/2d-page.protein
3DMET	False	http://identifiers.org/3dmet
ABS	False	http://identifiers.org/abs
AFTOL	False	http://identifiers.org/aftol.taxonomy
AGD	False	http://identifiers.org/agd

and of course you can filter elements as usual, for example here to see the resources suitable for citations:

resources = get_miriam_resources()
resources[resources.is_citation == True]

	is_citation	uri
resource
DOI	True	http://identifiers.org/doi
ISBN	True	http://identifiers.org/isbn
PubMed	True	http://identifiers.org/pubmed
arXiv	True	http://identifiers.org/arxiv

Displaying Annotations:

Now we load a fully annotated model, to display its annotations:

load_biomodel(64);

Then we can display the Notes of the model:

display(HTML(get_notes()))

Similarly, we could get to all annotations. As with the get_notes call, if no element is specified, the annotations of the model element will be displayed:

get_miriam_annotation()

To display the annotations of a specific species, or reaction just enter its name as the element to get the information for. Here we do this for NADH to return the dictionary of descriptions as given:

get_miriam_annotation(name='NADH')

{'descriptions': [{'id': 'C00004',
   'qualifier': 'is',
   'uri': 'http://identifiers.org/kegg.compound/C00004',

   'qualifier': 'is',
   'uri': 'http://identifiers.org/chebi/CHEBI:16908',
   'resource': 'ChEBI'}]}

Setting annotations

Lets start over with a new model, and annotate it as we go along:

new_model(name='simple model', notes='A simple decay model');

The set_miriam_annotation accepts the following arguments:

• creators: a list of creator dictionary entries with: first_name, last_name, email and organization

• references: a list of reference dictionary entries with: id, uri, resource and description

• descriptions: a list of description dictionary entries with: qualifier, resource and id

• modifications: a list of DateTime objects representing the modification dates

• created: a DateTime object representing the creation date

• replace: a boolean indicating, whether the current annotation entries should be replaced (‘True’ default), or if new entries should be added to the existing ones (‘False’)

set_miriam_annotation(creators=[
    {
        'first_name': 'Frank',
        'last_name': 'Bergmann',
        'email':'fbergman@caltech.edu',
        'organization':'Heidelberg University'
    }], replace=True)

get_miriam_annotation()
