Tips and Tricks

Converting checkpoint files from G03 format to G09 format:
G09 cannot read G03 checkpoint files, so if you wish to use a G03 checkpoint file as the starting point for a G09 calculation, you first need to convert the file to the G09 checkpoint file format. Fortunately, Gaussian provides a utility for this called c8609. To use it you simply write
$ c8609 g03_checkpoint_file.chk
NOTE that this utility overwrites the original file, so if you want to keep the original file then you need to make a copy first!
