IndexError: single positional indexer is out-of-bounds

Hi all,

I encountered this error message:

multiprocessing.pool.RemoteTraceback:
"""
Traceback (most recent call last):

The above exception was the direct cause of the following exception:

Traceback (most recent call last):

results = phf.identify(args.input, args.mismatch, args.aligner, args.report, args.table, args.unknown, args.num_threads)

May I learn hot to fix it? Many thanks!
