[DFTB-Plus-User] triplet excitations

[Mat Toliday]

 Hello,
Have you set the spin to collinear and provided spin constants for your atoms?Mat

I want to run calculation fortriplet excitations, here is the Casida block
  Casida{
    Symmetry = triplet
    NrOfExcitations = 100
    StateOfInterest = 1
    WriteTransitions = Yes
    WriteTransitionDipole = Yes
  }
I got the following error:
-> The following 1 node(s) have been ignored by the parser:
(1)
Path: dftb_in/ExcitedState/Casida/Symmetry
Line: 38-38 (File: dftb_in.hsd)

PS: It works fortriplet excitations

Regards,Taoufik
