2-el transition densities for MS-CASPT2 JobMix

Dear developers/users

It seems that RASSI doesnt print the 2-el transition densities , when given the (X)MS-CASPT2 JobMix , with the HEFF keyword. The resulting TRD files only contain  the 1-el transition density at  bottom. My input is

&RASSI
HEFF
TRD2

If i remove the HEFF keyword, I do get the 2-el transition densities, but in this case RASSI rediagoaizes the JobMix and I get the densities of CASSCF wavefunctions. Is there a way to get the 2-el transition densities for the CASPT2 JobMix wavefunctions ?

Re: 2-el transition densities for MS-CASPT2 JobMix

Probably not. With HEFF (or EJOB) you're saying, among other things, that you don't want RASSI to compute the Hamiltonian matrix, and therefore I guess it will skip 2-electron integrals (and TDMs) because they're not needed.
