Selected CI from a previous MCSCF computation error


Clicked A Few Times
Dear developers and users of NWChem,

I am new to the field of multiconfigurational methods and trying to do selected CI, pick as an initial CI reference the previously executed MCSCF. The MCSCF converged normally, but when I tried to do CI, the following error was encountered:

Last few lines for the output file for CI:
