Chemical Fingerprint

StreamableChemAxon/Infocom JChem Extensions version 4.0.0.v192100 by Infocom Corporation

The fingerprints encode the topological connection between atoms of the chemical graph. Though such encoding loses information, still it preserves enough to allow fast comparisons of chemical structures without their direct structural comparison but instead involving their topological fingerprints.

Options

Fingerprint length
The number of bits in the bit string.
Maximum pattern length
The maximum length of atoms in the linear paths that are considered during the fragmentation of the molecule.
Bits to be set for patterns
After detecting a pattern, some bits of the bit string are set to "1". The number of bits used to code patterns is constant.
Structure column
The structure column.

Input Ports

Input table that contains structure in Structure(Mrv, Sdf, Smiles, etc.) format.

Output Ports

Output table that contains Chemical Fingerprint descriptors.
