Cclib.jl is a Julia wrapper around Cclib - an open source library written in Python for parsing and interpreting the results of computational chemistry packages.


  • Parsing outputs from 15 different programs: ADF, DALTON, Firefly, GAMESS (US), GAMESS-UK, Gaussian, Jaguar, Molpro, MOLCAS, MOPAC, NWChem, ORCA, Psi4, NBO, QChem and Turbomole.

  • Further analysis of calculation outputs, such as population analysis.

  • Integration with AtomsBase.jl - an interface for atomic geometries.

  • Integration with Fermi.jl - quantum chemistry framework written in Julia.
