PR updating the
fastq_strand.pyutility to handle the case whenSTARcompletes successfully but no reads from the input Fastqs are mapped. In this case the total count of mapped reads is zero and this results in aZeroDivisionexception fromfastq_strand.py.With this update, the program will instead report the forward and reverse psuedo-percentages as both being zero and complete without an error.
