1475    
1476    Return the evidence for a functional coupling.
1477    
1478    A pair of features is considered evidence of a coupling between two other
1479    features if they occur close together on a contig and both are similar to
1480    the coupled features. So, if B<A1> and B<A2> are close together on a contig,
1481    B<B1> and B<B2> are considered evidence for the coupling if (1) B<B1> and
1482    B<B2> are close together, (2) B<B1> is similar to B<A1>, and (3) B<B2> is
1483    similar to B<A2>.
1484    
1485    The score of a coupling is determined by the number of pieces of evidence
1486    that are considered I<representative>. If several evidence items belong to
1487    a group of genomes that are close to each other, only one of those items
1488    is considered representative. The other evidence items are presumed to be
1489    there because of the relationship between the genomes rather than because
1490    the two proteins generated by the features have a related functionality.
1491    
1492    Each evidence item is returned as a three-tuple in the form C<[>I<$peg1a>C<,>
1493    I<$peg2a>C<,> I<$rep>C<]>, where I<$peg1a> is similar to I<$peg1>, I<$peg2a>
1494    is similar to I<$peg2>, and I<$rep> is TRUE if the evidence is representative

1622    coupling ID. All that we know for sure about it is that it can be
1623    generated easily from the feature IDs and the order of the IDs
1624    in the parameter list does not matter (i.e. C<CouplingID("a1", "b1")>

2248    
2249    Properties are arbitrary key-value pairs associated with a feature. (At some point they
2250    will also be associated with genomes.) A property value is represented by a 4-tuple of
2251    the form B<($fid, $key, $value, $url)>. These exactly correspond to the parameter
2252    
2253    =over 4
2254    
2255    =item fid
2256    
2257    ID of the feature possessing the property.
2258    
2259    =item key
2260    
2261    Name or key of the property.
2262

2265    Value of the property.
2266    
2267    =item url

2270    empty string if no such document exists.
2271    
2272    =back
2273    
2274    The parameters act as a filter for the desired data. Any non-null parameter will
2275    automatically match all the tuples returned. So, specifying just the I<$fid> will
2276    return all the properties of the specified feature; similarly, specifying the I<$key>
2277    and I<$value> parameters will return all the features having the specified property
2278    value.
2279    
2280    A single property key can have many values, representing different ideas about the
2281    feature in question. For example, one paper may declare that a feature C<fig|83333.1.peg.10> is
2282    virulent, and another may declare that it is not virulent. A query about the virulence of
2283    C<fig|83333.1.peg.10> would be coded as
2284    
2285        my @list = $sprout->GetProperties('fig|83333.1.peg.10', 'virulence', '', '');
2286    
2287    Here the I<$value> and I<$url> fields are left blank, indicating that those fields are
2288    not to be filtered. The tuples returned would be
2289    
2290        ('fig|83333.1.peg.10', 'virulence', 'yes', 'http://www.somewhere.edu/first.paper.pdf')
