**What it does**

This tool clips adapters from the 3'-end of the sequences in a FASTA/FASTQ file.

--------


**Clipping Illustration:**

.. image:: fastx_clipper_illustration.png

**Clipping Example:**

.. image:: fastx_clipper_example.png

**In the above example:**

* Sequence no. 1 was discarded since it wasn't clipped (i.e. didn't contain the adapter sequence). (**Output** parameter).
* Sequence no. 5 was discarded --- it's length (after clipping) was shorter than 15 nt (**Minimum Sequence Length** parameter).
