In BioMedR: Generating Various Molecular Representations for Chemicals, Proteins, DNAs/RNAs and Their Interactions

Description

Calculate the FP4 Molecular Fingerprints

Usage

extrDrugOBFP4(molecules, type = c("smile", "sdf"))

Arguments

molecules	R character string object containing the molecules. See the example section for details.
type	'smile' or 'sdf'.

Examples

mol1 = 'C1CCC1CC(CN(C)(C))CC(=O)CC'  # one molecule SMILE in a vector
mol2 = c('CCC', 'CCN', 'CCN(C)(C)', 'c1ccccc1Cc1ccccc1',
         'C1CCC1CC(CN(C)(C))CC(=O)CC')  # multiple SMILEs in a vector

smifp0 = extrDrugOBFP4(mol1, type = 'smile')
smifp1 = extrDrugOBFP4(mol2, type = 'smile')
