Silicos is pleased to announce the release of version 3 of its  
molecular filtering software Sieve. Sieve is a program for filtering  
out molecules with unwanted properties. It is based on the Open Babel  
open source C++ API (version 2.3) for rapid calculation of molecular  
properties. The program comes with a number of pre-programmed  
molecular properties that can be used for filtering. These properties  
include, amongst others:
        • Physicochemical parameters, such as logP, topological polar surface  
area criteria, number of hydrogen bond acceptors and donors, and  
Lipinski's rule-of-five;
        • Graph-based properties, including ring-based parameters and  
rotatable bond criteria;
        • Selection criteria by means of smarts patterns;
        • Similarity criteria;
        • Three-dimensional distances between user-definable fragments;
        • Criteria based on molecular titles and/or SDF-tags
Sieve is a command line-driven program that is instructed by means of  
command line options and a user-definable filter file. The source code  
is released under the terms of the GNU General Public License as  
published the Free Software Foundation version 2 of the License. It  
can be downloaded from www.silicos.com or openbabel.org/wiki/
