extract_fasta_bins.py uses pandas read_csv that automatically converts numeric IDs to strings. If you have a lot of contigs from different assemblies, it is more convenient to renumber them with numeric IDs, and this will cause extract_fasta_bins.py to fail with a KeyError as the sequence IDs are strings at one point and integers at another, and so the IDs can not be found.
