+**What this tool does**
 
-  This tool computes several physico-chemical properties for a set of molecules.
+Computes several physico-chemical properties for a set of molecules.
+
+The following physico-chemical properties and descriptors are computed for each molecule:
 
------
+	- number of hydrogen-bond donor and acceptor groups
+
+	- number of rotatable bonds
 
-.. class:: warningmark
+	- logP
+
+	- number of rings
 
-**Tip:** the generation of Spectrophores(TM) requires the previous addition of explicit hydrogen atoms and the proper definition of 3D coordinates. The user is directed towards the corresponding tools if accurate Spectrophores(TM) descriptors are required.
+	- number of heavy atoms
+
+	- molecular weight
 
------
+	- total Polar Surface Area
+
+	- molecular refractivity
 
-.. class:: infomark
+	- Canonical SMILES
+
+	- InChI string
 
-**Input:** molecular file in sdf or mol2 format files. The input file may contain multiple molecules. 3D coordinates of the files have to be provided.
+	- InChI-Key
 
-**Output:** this program generates an sdf file containing several computed physico-chemical properties stored as meta-data, or a tabular formatted file with the meta-data stored in columns.
