forgi.graph.transform_graphs module¶

This module has functions which take a Bulge-Graph as input and return a modified copy of it.

This is implemented as a class which is accessible as BulgeGraph.transformed. This way we can properly inherit in CoarseGrainRNA

class forgi.graph.transform_graphs.BGTransformer(bg)[source]¶

Bases: object

condensed()[source]¶

Return a condensed copy of the BulgeGraph.

In the condensed BulgeGraph only the first (most 5-prime) nucleotide or base-pair of each element is retained, and the other nts/ base-pairs are converted to missing residues. In basepairs the first basepair contains the most 5’ and most 3’ nucleotide of the stem.
