+This tool clips adapter sequences from a fastq file and outputs either a    
+fasta or fastq file of clipped reads with renumbered fasta/fastq headers.
+
+Clipped sequences with Ns can be discarded.
+
+Min size and max size filter clipped reads on their size.
+
+Note that unclipped reads that satisfy the min and max size conditions are kept.
