bsxplorer.Genome.exon

Genome.exon(min_length: int = 100) → DataFrame[source]

Filter annotation by type == exon and length threshold.

Warning

This method will have empty output, if type is not specified in input file.

Parameters:: min_length – Region length threshold.
Return type:: Return polars.DataFrame for downstream usage.

Examples

>>> path = "/path/to/genome.gff"
>>> genome = genome.from_gff(path)
>>> genome.exon(min_length=200)
shape: (132_822, 7)
