Difference between fastani_ani and closest_placement_ani #602

Hi @donovan-h-parks

I have gtdbtk.bac120.summary.tsv file for the MAGs, the file has two columns for ani; one is fastani_ani and the other is closest_placement_ani. Why are there two columns for ANI and which one to consider fastani or closest placement?. The ones which have the ani values in fastani_ani have NA as values in the closest_placement_ani column and vice-versa. And same is happening for the Reference genomes.

Thanks in Advance Saraswati
