Hi,

I have a problem restarting a conical intersection optimization. When I
read in a wfu-file from a former optimization for the optimization of a
conical intersection the GD vector is set to zero:

_ Gradient Difference_
_ 0.0000000000 0.0000000000 0.0000000000_
_ 0.0000000000 0.0000000000 0.0000000000_
_ 0.0000000000 0.0000000000 0.0000000000_
_ 0.0000000000 0.0000000000 0.0000000000_
_ 0.0000000000 0.0000000000 0.0000000000_
_ 0.0000000000 0.0000000000 0.0000000000_
_ 0.0000000000 0.0000000000 0.0000000000_
_ 0.0000000000 0.0000000000 0.0000000000_
_ 0.0000000000 0.0000000000 0.0000000000_

and subsequently the Overlap is:

 _Overlap between normalized GD and DC: NaN_

my input is:

_file,2,coin_opt7_6_5_3.wfu_
