.. class:: infomark

**TIP**. To return sequences longer than a certain length, set *Minimal length* to desired value and leave *Maximum length* set to '0'.

-----

**What it does**
	
Outputs sequences greater than or equal to *Minimal length* and less than or equal to *Maximum length*. 
 
-----

**Example**

Suppose you have the following FASTA formatted sequences::

	&gt;seq1
	TCATTTAATGAC
	&gt;seq2
	ATGGC
	&gt;seq3
	TCACATGATGCCG
	&gt;seq4
	ATGGAAGC

Setting the **Minimal length** to **10**, and the **Maximum length** to **0** will return all sequences longer than 10 bp::

 	&gt;seq1
	TCATTTAATGAC
	&gt;seq3
	TCACATGATGCCG
