alifestd_mark_ancestor_origin_time_asexual

alifestd_mark_ancestor_origin_time_asexual(phylogeny_df: DataFrame, mutate: bool = False, *, mark_as: str = 'ancestor_origin_time') → DataFrame

Add column ancestor_origin_time.

The output column name can be changed via the mark_as parameter.

Dataframe must provide column origin_time.

A topological sort will be applied if phylogeny_df is not topologically sorted. Dataframe reindexing (e.g., df.index) may be applied.

Input dataframe is not mutated by this operation unless mutate set True. If mutate set True, operation does not occur in place; still use return value to get transformed phylogeny dataframe.
