Why the keyword noscf didn't work?

Helina,

For the following input deck the "noscf" keyword seems to be working properly. This case was run with the current NWChem 6.1.1 release version.

Bert

start he2

geometry
he 0 0 0
end

basis
he library cc-pvdz
end

scf
uhf
vectors output he.movecs
end

task scf

geometry
he 2 0 0
he -2 0 0
end

scf
uhf
singlet
vectors input fragment he.movecs he.movecs output dimer.movecs
noscf
end

task scf

Dear all,

I am a new user of NWChem. I tried to obtain the combined wavefunction file from the two fragments, and calculated the hartree-fock energy without updating the wavefunction. However, the program seems to ignore the keyword 'noscf' and still perform many scf steps to turn the charge localized states to delocalized states. Could you tell me how to fix this problem? Thank you very much for your help!!
