how can Gaussian 98 input files be made compatible with Gaussian 03/ 09 so that the same can be used for calculations
Hi,
You can use the Formchk utility by simply typing: formchk [name of the binary checkpoint file to be formatted] [the name for the resultant file output], for example:
$ formchk file1.chk file2.fchk
Best,
Dear Anand Bharadvaja,
To my knowledge, the input files for Gaussian 98, Gaussian 03 and Gaussian 09 are the same. There is no need for any conversion.
Hoping this will be helpful,
Rafik
