+**What it does**
+
+This tool creates a histogram image of sequence lengths distribution in a given fasta data set file.
+
+**TIP:** Use this tool after clipping your library (with **FASTX Clipper tool**), to visualize the clipping results.

+
+**Output Examples**
+
+
+In the following library, most sequences are 24-mers to 27-mers. 
+This could indicate an abundance of endo-siRNAs (depending of course of what you've tried to sequence in the first place).

+
+
+In the following library, most sequences are 19,22 or 23-mers. 
+This could indicate an abundance of miRNAs (depending of course of what you've tried to sequence in the first place).
