+Usage:

+options:
+-i input file# input reads fasta/fastq file
+-g input file# genome file
+-index file-prefix #(must be indexed by bowtie-build) The parameter
+                string must be the prefix of the bowtie index. For instance, if
+                the first indexed file is called 'h_sapiens_37_asm.1.ebwt' then
+                the prefix is 'h_sapiens_37_asm'.##can be null
+-v <int>           report end-to-end hits w/ <=v mismatches; ignore qualities,default 0;
+
+-p/--threads <int> number of alignment threads to launch (default: 1)
+
+-r int          a read is allowed to map up to this number of positions in the genome
+                default is 25
+
+-o output directory
