[molpro-user] save/start,task in frequency calculations

Dear all,

I'm playing with the "masktask" option (together with "save,task=record number" and "start,task=record number" ) in order to split in several jobs a time consuming numerical frequency calculation with MRCI.

Task restarting is working fine for the lowest state of a multi-state MRCI calculation, but unfortunately it fails for the excited states: the gradient norm is recalculated as not zero at equilibrium position and the hessian and resulting frequencies are wrong.  Log files with and without restart are yet identical for all tasks. I thus guess that the problem occurs in the numerical hessian calculation. Why?

Maybe that some flag (not reported in the manual) should be added in the save/start task directive?
I tried  … save,task=5500.2,state=2.1  … not rejected by the program … but giving the same incorrect results

Any help, example input would be welcomed
Many thanks in advance
