After sucessfull computation first bead. I've got error with second.
!! The overlap matrix has 12 vectors deemed linearly dependent with
eigenvalues:
7.28D-10 2.54D-08 2.79D-08 5.90D-08 3.11D-07 5.42D-07 8.67D-07 1.32D-06
1.76D-06 2.81D-06 4.23D-06 5.91D-06
------------------------------------------------------------------------
mcscf:linear dependent AO basis 0
------------------------------------------------------------------------
There is an error in the specified basis set
I think second bead geometry is wrong because when I run this task without midgeomery and set endgeom to midgeom all works fine.
How I can get all beads geometryes between startgeometry and midgeometry to verify my sugestion.
