Mona

Handling data sets of small molecules in various file formats is day to day routine task. You may trust a script or other black-box approach 90% of the time, but every now and then you certainly want to see what's going on. Mona is an interactive tool that can be used to prepare and visualize small-molecule datasets.

Mona has been built on top of the well-known Naomi[1] cheminformatics framework that has been proven to be robust, accurate and extremely efficient. Mona facilitates:

  • Loading molecules files stored in SDF, MOL2 or SMILES-format
  • Scanning entire directories for molecule data
  • 2D depiction of hundreds of thousands of molecules
  • Duplicate removal
  • Filtering based on physic-chemical properties, functional groups, and substructures
  • SMARTSediting and SMARTSmatch-visualization
  • Set-operations such as union, intersection, sub-set splitting
  • Visualization of property distributions

For the benefit of interactive use, Mona has been equipped with a database backend that allows for an extremely efficient handling. Upon import numerous physic-chemical properties are calculated and deposited in the database. For a million molecules this may take half an hour. However, once stored you may close and re-open the database within a matter of a minute or two, gaining instant access to all properties and high-quality 2D depictions.
