Bug Description
When the query sequence file contains zero sequences, _autotune_reads_per_batch fails (because it cannot grep an empty file evidently).

Steps to reproduce the behavior
See description and error message reported on forum

Expected behavior
_autotune_reads_per_batch (or maybe somewhere upstream) should catch this error and raise a more intuitive error message indicating that the inputs are empty.
