Currently, only Gaussian16 is supported. Although Gaussian16 users may separate the computational scratch folder and data folder, current QCforever requires that data folder is the same as the scratch. Because Gaussian tools, formchk and unfchk, are used for making fchk or chk files, the path to Gaussian should be suitably set before using QCforever. To count the number of radical electrons and the value of total charge from a sdf file, RDKit 18 are required. Other required python libraries are Numpy. To make the data for computing atomization energy, chemical shift from TMS, and oxygen orbital level, bash scripts are used.
