Psi4 (version: psi4-1.4a2.dev66+6e6) doesn’t write “Total DF-MP2 Density” to the fchk file when I use the below input file. How can I get the “Total DF-MP2 Density” in the fchk file?
molecule ABC {
0 1
# molecule coordinates ...
no_com
no_reorient
units angstrom
}
set {
basis aug-cc-pVTZ
scf_type df
guess sad
}
grad, wfn = gradient ('mp2', return_wfn = True)
fchk_writer = psi4.FCHKWriter(wfn)
fchk_writer.write ('molecule.fchk')
Any chance for you to update your psi4?
Then you should get the ‘Total CC Density’ label as a catch-them-all label for post-scf methods.
The MP2 density in the file will be correct, but the SCF density will be something else (natural MP2 orbitals)
I am currently working on a patch that will fix this and multiple other issues with the FCHK files.
Which version of the Psi4 should I install? Can you please provide me a link for that? And will it give me the “Total DF-MP2 Density” in the fchk file?
