# print_e_conv

> program that prints in a human readable format the convergence of the CIPSI algorithm.

> for all istate, this program produces

> - a file “EZFIO.istate.conv” containing the variational and var+PT2 energies as a function of N_det
> - for istate > 1, a file EZFIO.istate.delta_e.conv containing the energy difference (both var and var+PT2) with the ground state as a function of N_det

> Needs:

> `ezfio_filename` |  |
