Problems with restart
Dear NWChem users and developers,
I am trying to restart an old job and project onto a new larger basis set.
However, I have problems in loading the old vectors. Here is the error message:

!! nbf/nmo/basis-name mismatch
          nbf=1114 nbf_file=1097
nmo=1114nmo_file=1097
basis="small" basis_file="ao basis"

 Either an incorrect movecs file was
specified, or linear dependence has changed,
or the basis name was changed.

Loading old vectors from job with title :

Cr7Ni2Cu LDA primo tentativo di convergenza


 Load of old vectors failed.   Forcing atomic density guess


I also attach the input:

basis small
 * library sto-3g
end

basis large
  • library ahlrichs_vdz
end

set "ao basis" small

dft
 vectors input old.movecs output small.movecs
noscf
cgmin
rodft
mult 2
end
task dft

set "ao basis" large

dft
 grid fine
vectors input project small small.movecs output proj.movecs
print "final vectors"
iterations 100
cgmin
rodft
mult 2
end

task dft

Any suggestion?
Thanks to everybody
Alessandro
