If you have problems during the execution of MRCC, please attach the output with an adequate description of your case as well as the followings:
This information really helps us during troubleshooting
- the way mrcc was invoked
- the way build.mrcc was invoked
- the output of build.mrcc
- compiler version (for example: ifort -V, gfortran -v)
- blas/lapack versions
- as well as gcc and glibc versions

basis set cc-pvtz-ri-jk not found was created by rkanters
I am trying to do an ROHF-LCCSDT/cc-pVTZ calculation on a system with Si and Li atoms in it. (The MINP file is pasted below), and get the message:
Basis set cc-pvtz-ri-jk not found!
Fatal error in integ.
Program will stop.
The GENBAS I use is the one distributed with MRCC and does have the cc-pVTZ-RI-JK basis set for Si, but not for Li. I looked at the EMSL library ( bse.pnl.gov/bse/portal ) but could only find the cc-pVTZ-RI ones, whose Si functions are different from the cc-pVTZ-RI-JK in GENBAS.
Where can I find the cc-pVTZ-RI-JK basis set info for Li?
Thanks,
René

Dear René,
Unfortunately the RI-JK auxiliary basis set is missing from our GENBAS file. You can find it in the supplementary material for J. Comput. Chem. 29, 167, 2008.
On the other hand, please note that local CC methods are not implemented for open-shell systems, so you should perform a conventional CCSDT calculation (never mind, your system is relatively small, and probably the local CCSDT wouldn't be faster). It also resolves the first problem since for conventional CC calculations the density fitting approximation is not used and you don't need the auxiliary basis sets.

Dear Mihaly,
I got so excited when in the first paragraph of 6.8 in the manual I saw the orbital transformation availability for RHF and ROHF, that I didn't read the 2nd paragraph till the end where it does indeed state that the local methods are only available for RHF orbitals.

Sorry, I have just realized, the orbital-transformed approaches are available for RHF and UHF (not ROHF). It is a typo in the manual, we will correct it.
Nevertheless, you can also try these techniques to accelerate your CCSDT calculations.
