Dear all,

Just to inform everyone about a new free software that makes use of the CDK:
http://sa2.sourceforge.net/

This software is basically able to manage small to very large chemical  
libraries (we have millions of compounds in our in-house database),  
and any sets of properties associated with each molecules, through a  
MySQL database. Various chemoinformatics analysis can then be  
performed on top of the database.

It makes uses of the CDK-jcp nightly built picked up here (as I need  
depiction too):
http://pele.farmbio.uu.se/nightly-jcp/

It uses various CDK functionalities, including descriptors /  
fingerprints calculation, substructure search, 2D depiction, SMART  
macthing...

 From a developer point of view, it is based on the NetBeans Platform,  
and is therefore quite modular.

The software will be licensed under the GPL v2 license. Currently, the  
sources are not available yet, as I want to stabilize and document the  
API before releasing it.

FYI, and as asked by Egon, I've encountered various problems using the  
CDK during the development of the software, some of which are listed  
here:
- Atom types not recognized
- Various problems with SDF reader / writer, which have been fixed now  
for most of them I think.
- SMART matching problems, mainly a performance issue (I've run very  
basic tests comparing CDK, JOELib and Indigo for those who are  
interested in the details).
- Invalid SMILES reading (fixed now I guess)

An article is on its way too, but not submitted yet.

Cheers :)
