  • Batch computing limit : 500 molecules at one time.
  • Convert to 3D:
    • Check the option "Convert to 3D" if you wish to convert the 2D molecule to 3D molecule before computing descriptors. It is better to do this job using your own means than to rely on this software to do it. (You can obtain the 3D molecule via ChemMOP)
    • If you wish to compute 3D descriptors using molecule without 3D structure and check the option of 'No', ChemDes will force to use MM2 forcefield.
