Class MassToFormulaTool

java.lang.Object
org.openscience.cdk.formula.MassToFormulaTool
@Deprecated public class MassToFormulaTool extends Object
Deprecated.
Please use MolecularFormulaGenerator

Tool to determine molecular formula consistent with a given accurate mass. The molecular formulas are not validate. It only consist in generate combination according object (see MolecularFormulaChecker). The algorithm is published in Rojas-Cherto M. et.al. [Rojas-Cherto, Miguel et. al.. Bioinformatics. 2011. ]. 

   MassToFormulaTool mf = new MassToFormulaTool();
   double myMass = 133.004242;
   IMolecularFormulaSet mfSet = mf.generate(myMass);

The elements are listed according on difference with the proposed mass.

    • MassToFormulaTool

      public MassToFormulaTool(IChemObjectBuilder builder)
      Deprecated.
      Construct an instance of MassToFormulaTool. It is necessary because different matrix have to build. Furthermore the default restrictions are initiated.
