[guide-user] Re: quite basic question regarding CHARON.

Dear Octavi.

My guess is that you have the image file pp.st8 in a directory other than Guide.
Try naming the file with its complete name such as C:\ST8\pp.st8.

Also their is a newer version of Charon on the project pluto web page that
is a bit easier to use. You no longer have to input data on the command line.

Good luck.
