fasta_filter_by_length.py $input $min_length $max_length $output
.. 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 between *Minimal length* and *Maximum length*.
-----
**Example**
Suppose you have the following FASTA formatted sequences::
>seq1
TCATTTAATGAC
>seq2
ATGGC
>seq3
TCACATGATGCCG
>seq4
ATGGAAGC
Setting the **Minimal length** to **10**, and the **Maximum length** to **0** will return all sequences longer than 10 bp::
>seq1
TCATTTAATGAC
>seq3
TCACATGATGCCG
