relaxed densities not working in Molpro 2025.4

[Vili-Taneli Salo]

Hi,

According to the manual, I should be able to calculate relaxed ground state densities with the df-cc2 method

Link to the manual:

https://www.molpro.net/manual/doku.php?id=the_closed-shell_density_fitting_cc2_program_for_ground_and_excited_states&s[]=cc2#computing_cc2_ground_state_densities_and_gradients

However, when I do a test run, the program says the keyword "relaxed" is not recognized at all; program output:

Nodes          nprocs
 node119.cluster    3
 Distribution of processes:   nprocs(total)=    4   nprocs(compute)=    3   nprocs(helper)=    1

I wonder if anyone knows whether the relaxed densities are actually implemented, or if the keyword in the manual is wrong.

Best,
