Project Description
David's useful Unimod Wrapper
=============================


This is a simple python module to wrap the Unimod XML file in a readily
accessible form for python programemrs.
A copy of the unimod.xml file is included.

Dependencies
============
No dependencies that are not in a standard >2.4 python distribution.

Usage
=====

1. simple usage. Use the built in file.

>>> import Unimod.unimod
>>> db=Unimod.unimod.database

2. Use your own file
>>> import Unimod.Database
>>> db=Unimod.Database.Database(file="my unimod file")

3. Getting element info
Use the get_element(label) method and a dictionary is returned.
>>> db.get_element('H')
{'avge_mass': '1.00794', 'title': 'H', 'full_name': 'Hydrogen', 'mono_mass': '1.007825035'}

All labels are supported, and additionally the common isotopes as labels as well

>>> db.get_element('O')
{'avge_mass': '15.9994', 'title': 'O', 'full_name': 'Oxygen', 'mono_mass': '15.99491463'}
>>> db.get_element('18O')
{'avge_mass': '17.9991603', 'title': '18O', 'full_name': 'Oxygen18', 'mono_mass': '17.9991603'}
>>> db.get_element('16O')
{'avge_mass': '15.9994', 'title': 'O', 'full_name': 'Oxygen', 'mono_mass': '15.99491463'}

4. getting modification info

Use the get_label(modification) method
>>> db.get_label('Phospho')
{'delta_mono_mass': '79.966331',
'group_of_poster': 'admin',
'delta_avge_mass': '79.9799',
'username_of_poster': 'unimod',
'title': 'Phospho',
'delta_composition': 'H O(3) P',
'sites': {
'C': {'position': 'Anywhere', 'hidden': 'true', 'site': 'C', 'classification': 'Post-translational', 'spec_group': '5'},
'D': {'position': 'Anywhere', 'hidden': 'true', 'site': 'D', 'classification': 'Post-translational', 'spec_group': '3'},
'H': {'position': 'Anywhere', 'hidden': 'true', 'site': 'H', 'classification': 'Post-translational', 'spec_group': '4'},
'K': {'position': 'Anywhere', 'hidden': 'true', 'site': 'K', 'classification': 'Other', 'spec_group': '7'},
'S': {'position': 'Anywhere', 'hidden': 'false', 'site': 'S', 'classification': 'Post-translational', 'spec_group': '1'},
'R': {'position': 'Anywhere', 'hidden': 'true', 'site': 'R', 'classification': 'Post-translational', 'spec_group': '6'},
'T': {'position': 'Anywhere', 'hidden': 'false', 'site': 'T', 'classification': 'Post-translational', 'spec_group': '1'},
'Y': {'position': 'Anywhere', 'hidden': 'false', 'site': 'Y', 'classification': 'Post-translational', 'spec_group': '2'}
},
'spec_group': {
'1': ['T', 'S'],
'3': ['D'],
'2': ['Y'],
'5': ['C'],
'4': ['H'],
'7': ['K'],
'6': ['R']
},
'date_time_posted': '2002-08-19 19:17:11',
'date_time_modified': '2011-11-25 10:55:54',
'full_name': 'Phosphorylation',
'record_id': '21',
'approved': 'true'
}

In this dictionary are two fields, 'sites' which contains info for each amino acid, and 'spec_group' which contains the specificity grouping for the modification.

5. Searching for labels
Pass a regular expression in text form to the list_labels method.

>>> db.list_labels('.*Phospho.*')
['Phosphoguanosine', 'Phosphopantetheine', 'PhosphoHex', 'Phosphopropargyl', 'PhosphoribosyldephosphoCoA', 'PhosphoHexNAc', 'Phosphoadenosine', 'PhosphoUridine', 'Phosphogluconoylation', 'Label:13C(9)+Phospho', 'Phospho']
