Query Example
Find all features overlapping the base range 2000..3000:
to:
See the bioseg usage page for examples.
Code
The code is available in a subversion repository at Bioinformatics.org. It can be checked out with this command:
Changed lines 20-21 from:
select * from feature
where bioseg_create(2000, 3000) && bioseg_create(fmin, fmax);
to:
svn checkout svn://bioinformatics.org/svnroot/bioseg/trunk bioseg
Changed lines 22-60 from:
or:
select * from feature
where '2000..3000'::bioseg && bioseg_create(fmin, fmax);
The "&&" is the overlaps operator, the README for a full list of operators.
Index Creation
The speed of the query above will be improved by creating a function index:
create index test on feature using gist (bioseg_create(fmin, fmax));
Using the bioseg type directly
The bioseg type can be used as a column type. eg.
CREATE TABLE test_bioseg (id integer, name text, seg bioseg);
and populated like this:
insert into test_bioseg values (1, 'some_name', '1000..2000'::bioseg);
then queried:
select * from test_bioseg where seg && '200..3000'::bioseg;
There are more example queries in sql/bioseg.sql.
