WARNING: If you choose to "Create file with _count added to sequence names" and any of your sequence names end in "_" followed by numbers (for example, "NC_123456"), the numbers will be treated as occurrence counts. For best results (if these numbers don't actually represent counts), add an extra character to such sequence names (e.g. "NC_123456x").
