There are numerous tools outside and list of lists of hundreds of programs. This page covers only covers a very limited number of those tools I could use. This says nothing about the quality of many other packages.The main tools for molecule handling in our lab is the ChemAxon Marvin suite.
Visualization
- Marvin Space - MSpace (ChemAxon)
- ArgusLab, VEGA
- Mview (ChemAxon)
- Instant-JChem (multiple molecules from SMILES, SDF, RDF)
- BioClipse for spectra and molecules (CML)
QSAR
