Re^2: Is it possible to define 2 or more bases for 1 atom type in BASIS.LIB?

Alex Granovsky

Dear Wibren & Luca,

another solution is to use input file preprocessing feature of Firefly
as shown in this example (note it must be used together with -i command line option).
Please let us know if you need more details or comments on this.

Kind regards,
Alex Granovsky

>The problem arises when you try to load these two different basis set on the same type of atom, in your case carbon. As far as I know the only workaround is to manually define the basis set in the $DATA deck, like in the attached files (NewLinearDep), I know that it could be annoying with many atoms.
