The GUI program also aids in generating input files for the MO integral transformation in the DIRAC program. Specifically, the GUI provides a range of molecular orbitals to be transformed, located just below the 'Recommended MOLTRA setting' statement. Additionally, the GUI program estimates the required memory for CASPT2 calculations based on the selected orbital space, assisting users in constructing orbital spaces according to their available computational resources. For IVO calculations, an input file is automatically generated alongside the CASPT2/RASPT2 input file. Users also have an option to manually create a text-based input file.
