** Re^3: Some Questions on CI (GUGA) **

Dear PeterP,I agree the input of $transt is a bit ugly.

We'll see what can be done to simplify it.

As to CI on K-S DFT reference, it is possible. You need to add

$contrl wide=.t. $end

to your dft energy run, then pick up the complete $vec group

from the punch file, add it to the input file, and in addition add:

$contrl scftyp=none dfttyp=none cityp=guga (or aldet) $end
$guess asis=.t. guess=moread norb= put here the total number of MOs

and then run the second job.

Hope this helps.

Kind regards,

Alex Granovsky

>thank you for the help and the examples. I managed to set up my calculations correclty and get all the requested informations. Indeed one can't get these data from an prior RUNTYPE=ENERGY job but one need's to use RUNTYPE=TRANSITN. The input-file for my Nitrobenze example than needs to look like this:
