.. class:: infomark

**What this tool does**

Parses a molecular file and adds hydrogen atoms at a user-defined pH value.

* Protocol::

	1. The hydrogen atoms included in the input molecule are deleted.
	2. Protonation state is predicted at the target pH and the corresponding hydrogen atoms added accordingly.

-----

.. class:: infomark

**Input**

3D format files are required, e.g. SDF_

.. _SDF: http://en.wikipedia.org/wiki/Chemical_table_file

-----

.. class:: warningmark

**Hint**

To avoid possible crashes, only molecules with more than five heavy atoms are parsed.

-----

.. class:: infomark

**Output**

Same output format as the input format.
