get_presence_gcf_strain

get_presence_gcf_strain(
    gcfs: Sequence[GCF], strains: StrainCollection
) -> DataFrame

Get the occurrence of strains in gcfs.

The occurrence is a DataFrame with GCF objects as index and Strain objects as columns, and the values are 1 if the gcf occurs in the strain, 0 otherwise.
