gffutils.interface.FeatureDB.children_bp

FeatureDB.children_bp(feature, child_featuretype='exon', merge=False, merge_criteria=(<function seqid>, <function overlap_end_inclusive>, <function strand>, <function feature_type>), **kwargs)

Total bp of all children of a featuretype.

Useful for getting the exonic bp of an mRNA.

Parameters:

• feature (str or Feature instance) –

• child_featuretype (str) – Which featuretype to consider. For example, to get exonic bp of an mRNA, use child_featuretype='exon'.

• merge (bool) – Whether or not to merge child features together before summing them.

• merge_criteria (list) –

  List of merge criteria callbacks. All must evaluate to True in order for a feature to be merged. Only used if merge=True. When modifying this argument, you may want to use:

  from gffutils import merge_criteria as mc

  to access the available callbacks.

Return type:

Integer representing the total number of bp.
