1. Firefly does not have TPSS functional implemented.
2. Go to "Downloads" section of Firefly web server, near the end of the page you'll find archives with Ahlrichs' basis sets definitions.
Download them and construct a mixed basis set picking up appropriate
definitions and changing basis set names to something like "mixed".
It is sufficient to pick up only those elements you are using in your
$data group. Save your basis set definition to any file filename
Add the following line:
$basis gbasis=mixed extfil=.t. $end
and then provide the $data group as usual.
Finally run Filefly and add the -b option as follows:
firefly options -b filename
Note you may need to use fully qualified file name for filename
Hope this helps.
Kind regards,

I remember to read in some place that Firefly does not have Def2-* basis set implemented, can someone provide me an example on how to use external basis sets and how to set them for each atom?
