c8603

The c8603 utility converts checkpoint files from Gaussian 86 through Gaussian 98 to Gaussian 03 format. It takes the name of the checkpoint file as its argument, and transforms it in place, so that the reformatted file has the same name as the original one. For example, the following command converts the checkpoint file taxol.chk in the Gaussian scratch directory to Gaussian 03 format:

$ c8603 $GAUSS_SCRDIR/taxol.chk
