CCL: Wavefunction file for GAMESS



For Firefly v8 the AIMPAC variable was changed to be integer, rather than logical. Instead of AIMPAC=.t. one should now use AIMPAC=1 In addition, it is possible to set AIMPAC=2, this will change printout for UHF wavefunctions to print separate data for alpha and beta orbitals rather than unified data for UFH natural orbitals.

Yes, the keyword is still there.  Including AIMPAC=.TRUE. in your $CONTRL section will tell GAMESS to punch a WFN file.

Best,

Years ago I was working with GAMESS it had a keyword for making wfn files. It was simply Bader. But honestly I haven't worked with GAMESS for years. I hope it's still there. 

 

Good luck,

You may try using some options of GAMESS to print MO coefficients into its output file,
then take MOLDEN to open it and save in a .molden format.
Finally, use Molden2AIM ( http://people.smu.edu/wzou/program/ ) to convert .molden file to .wfn.
Some quantum chemistry codes may have different basis function normalization
conventions. To check that your .molden file is OK, JANPA program can help ( http://janpa.sf.net ) -
it checks for basis function normalization and orthogonality at the beginning of calculations.

G09 has straight forward keyword for generation .wfn file. Can anybody know similar keyword for GAMESS
or FIREFLY
