Small molecule structural similarity analysis and clustering

The program for analysis of high-throughput screening data and generally for analysis of data sets containing multiple chemical compounds. This software is most suitable for finding related chemical structures and for establishing structure-activity relationships (SAR) within experimentally generated molecule sets or libraries of small molecules.
1. Simple in use.

2. Fast performance.
    
3. The chemical similarity searches go beyond detection of just a common scaffold. The program can find
     non-obviously related compounds. To learn more, read about Tanimoto scoring and Open Babel.

4. Easy DragDrop-based SDF clustering with minimum tuning or setup steps.
MassiveSAR Structure-Activity analysis software (freeware) graphical user interface (GUI)
The input: a SMILES string and an SDF database containing many small molecules.
The output: a list of similarity indexes between the SMILES query and each molecule in the SDF file.

small molecule analysis and clustering functions

- Find molecules in SDF databases by SMILES string
- Cluster any SDF datasets by related chemical scaffolds
- Work with and sort SDF databases by SDF tags (such as hit scores, MW, etc)
- Add new SDF tags to SDF databases
- Extract SDF structures of interest from large SDF databases by using structure names or tags
- Extract SDF tags
- Split/Merge SDF data sets
- One-step SDF <-> SMILES conversion for any dataset sizes
