How to getExactMass() of a molecule?

This may be a dumb question.

But how do I get the exact mass of a molecule?

import chemaxon.struc.Molecule;
Molecule m = ....;

I can get the average mass of the molecule --> m.getMass();

But I am unable to access the exact mass --> m.getExactMass();


Do I need an additional license?
Am I missing something truly basic?

Thanks,
Guy

Hi,

I have moved the topic to the appropriate forum. The Marvin experts will respond soon.

This method works fine for me in JChem 5.2.6.

Hi,

But I am unable to access the exact mass --> m.getExactMass();

Could you share some more details on this ?

Do you get an exception maybe ? Can you paste here the full stack trace in that case ?

Thanks,
