Hello,
first: ricc2 supporsts the -proper flag only since TM V 5.10, older versions only accept the -fanal option and require the
$anadens data group in the control file
since TM V5.10 the -proper flag should work also for ricc2, but not that
-- it requires the calculation of a correlated density (if you just request a MP2 calculation without a gradient,
there is nothing to plot for ricc2, which you can't plot via dscf...) and as there is (as for the other programs)
no further input for the -proper option, the state for which the density is written to the interface files
must be uniequely defined via the 'geoopt model=xxx' option
-- you can give all the options for the generation of plot files already in the calculation of the gradient, but if
you use 'ricc2 -proper' after the gradient calculation it requires (as rimp2) that the density file (gsdens for
ground states and exdens for excited states) was kept
Thus, you either used TM V5.9.1 (or an older version) or the density files where not present because they have either not been calculated (not geoopt flag) or were lost...
