Mychem 0.8.1: more than just a bug fix

Mychem 0.8.1 has been released on 2010-09-07.

This version fix an important bug. All functions using serialized obmol type were impacted. The problem has been resolved by using the solution published by the pgchem project.

Mychem is now fully usable with MySQL 5.0 and 5.1. It should also be working with MySQL 4.1, but it has not been tested.

The bug list is now empty. I'm waiting for new providers!

  • New functions:

    • strip_salts

    • molecule_to_canonical_smiles

The Tanimoto function has been enhanced by two methods. The first was to store the
fingerprint as binary string. The second was to implement directly the tanimoto algorithm. Now, the Tanimoto coefficient computation of more than 70.000 entries takes less than 0.4 second on my laptop.


At least, a short article has been published about Pgchem and Mychem on Alchem.org.
