#Explanation of terms:
#bowtie2 -q -x <bt2-idx> -U <r> -S <sam>
#-q query input files are in fastq format
#-x <bt2-idx> Indexed "reference genome" filename prefix (minus trailing .X.bt2).
#-U <r> Files with unpaired reads.
# The default of bowtie2, is to write the output of the alignment to the terminal.
# Also, bowtie does not write BAM files directly, but SAM output can be converted to BAM on the fly by piping bowtie's output to samtools view.
# samtools options
# -b output BAM
# -q <integer> : discards reads whose mapping quality is below this number
