The DFTB+ code needs parameterisation data (Slater-Koster files) in order to perform calculations. These parameters are not distributed with the code.

You can download the Slater-Koster files from The Slater-Koster files are distributed under a different licence  from DFTB+, so you will have to sign a separate licence agreement to obtain these files. Please note that your account to download parameters at the site is separate to any account you may have at
