:orphan: Restarting SCF calculations =========================== A DIRAC calculation can be restarted at various stages depending on the type of calculation. In general it should be enough to give the archive file of a previous calculation as an argument to the ``pam`` script. DIRAC will then find and use the available data for restart. Alternatively you can copy restart files in using ``pam --put`` and if DIRAC finds them in the scratch directory, it will automatically restart from them. In general the program can restart from - ``DFCOEF`` Contains orbital coefficients in machine-readable format, and will be used for restarting the SCF procedure. - ``DFPCMO`` Contains orbital coefficients in human-readable format, and will be used for restarting the SCF procedure. - ``PAMFCK`` The Fock matrix. Will be used for restarting the SCF procedure. - ``AOPROPER`` Contains one-electron integrals. - ``X2CMAT`` Contains four- to two-component transformation matrices, and allows you to skip the transformation step of a two component calculation.
