RASSI module with GASSCF

Dear all,

I am using GASSCF to modelate the double core-hole states, so the same with single core-hole states.
Is it possible to use RASSI module to calculate some properties I need using GASSCF instead of RASSCF wavefunctions? The problem is that the do not have the same number of configurations:

()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()()

                                               &RASSI

                                   only a single process is used
                      available to each process: 2.0 GB of memory, 16 threads

  not bother with the RAS1..RAS3 arrays in that case. RASSI will reset these arrays as needed.)

Re: RASSI module with GASSCF

It looks so that using of the GASSCF states is not implemented in RASSI
