+**What does this tool do?**
+
+This tool computes the Euclidean distance between the Spectrophores(TM) descriptors of the target to each molecule stored in the library.
+
+|Spectrophores (TM)| search
+		|Spectrophores (TM)| is a screening technology by Silicos_ which converts three-dimensional molecular property data into one-dimensional spectra. Typical characteristics that can be converted include electrostatic potentials, molecular shape, lipophilicity, hardness and softness potentials. The computation is independent of the position and orientation of a molecule and allows an easy comparison of |Spectrophores (TM)| of different molecules.
+
+		Molecules with similar three-dimensional properties and shape, and therefore also similar biological activities, always have similar |Spectrophores (TM)|. As a result this technique is a very powerful tool to investigate the similarity of molecules and can be applied as a screening tool for molecular databases, virtual screening, and database characterisations.
+
+*Advantages:*
+
+- |Spectrophores (TM)| can realistically compute ligand-protein interactions based on aforementioned molecular descriptors
+- |Spectrophores (TM)| can be applied in both a ligand- or target-based setting
+- |Spectrophores (TM)| can distinguish, if needed, between the different enantiomers of stereo-selective compounds
+- |Spectrophores (TM)| can be computed fast

+
+**Hint** this tool is useful to select compounds with similar chemical features to a target, but accounting for the discovery of diverse scaffolds. This is in contrast to the results expected in a similarity search based on atom connectivity.
+

+
+.. class:: infomark
+
+**Input**
+
+The target molecule must be a SD formatted file with the |Spectrophores (TM)| descriptors stored as metadata. Such files can be generated using the *Compute physico-chemical properties* tool.
+
+-----
+
+.. class:: infomark
+
+**Output**
+
+The library of compounds is a tabular file with one line per compound. One column contains the |Spectrophores (TM)| descriptors.
