ailist.AIList.intersect_from_array#

AIList.intersect_from_array(self, const long[::1] starts, const long[::1] ends, const long[::1] ids)#

Find interval indices overlapping given ranges

Parameters:

starts : numpy.ndarray{long}: Start positions of intervals
ends : numpy.ndarray{long}: End positions of intervals
ids : numpy.ndarray{long}: ID of intervals

Returns:

ref_indexnp.ndarray{int}
Overlapping interval indices from AIList

query_indexnp.ndarray{int}
Overlapping interval indices from query AIList
.. warning:: – This requires construct() and will run it if not already run. This will re-sort intervals inplace.

Examples

>>> from ailist import AIList
>>> ail1 = AIList()
>>> ail1.add(1, 2)
>>> ail1.add(3, 4)
>>> ail1.add(2, 6)
>>> ail1
AIList
  range: (1-6)
   (1-2, 0)
   (3-4, 1)
   (2-6, 2)
>>> ail2 = AIList()
>>> ail2.add(1, 2)
>>> ail2.add(3, 6)
>>> ail2

  range: (1-6)
    (1-2, 0)
    (3-6, 1)
>>> q = ail1.intersect_from_array(ail2)
>>> q
