An integrated web-based platform for molecular descriptor and fingerprint computation

  BlueDesc Descriptor Calculator

  Use SMILES to calculate molecular descriptors

Example Draw

  Upload file (Formats: *.smi, *.sdf)


  • Usage: Click here for help when you meet a problem.
  • Batch computing limit : 500 molecules at one time.
  • About the forcefield : The BlueDesc works on 3D structure only. Here, we provide two methods. Users can upload the '*.sdf' file with 3D structures, or upload the '*.smi' file and choose one forcefield to optimize them. (a quick local optimization from Pybel is carried out with 500 steps and the chosen forcefield.) .
