A molfile is a table containing atom type, @C01274@ and a more or less arbitrary 2D or 3D information about a molecule. Well-known file formats include the MOLfile used by MDL Information Systems Inc. (e.g., in the database MACCS), the MOL2 file used by Tripos Associates (e.g., in the modeling package SYBYL), or the CSSR format.
