Hello all,

i want to optimize first in internal coordiantes(sequence dscf, grad, stapt) and after some steps (in the same directory) with cartesian coordiantes.
During the switch I loose the information about the index of energy and gradient. The step counter starts from 1 again and delete the former steps in energy and gradient.

I have tried to do it following way: (I have a define with internal coordiantes first)
adding to control file:
$optimize
 internal   off
 redundant  off
 cartesian  on

kdg hessapprox
and remove optinfo file

-> with deleting optinfo, I also loose the information about the optimization (and therefore also energy change as criteria is lost), but I want to keep that info especially for file energy and gradient.

Is there any idea/easy fix to have mixed information in energy and gradient file?

Thanks in advance,
Robin
