[Insight-users] Registration : how to begin?

[Luis Ibanez]

Hi Magda,

Please note that this example expects
you to create the output directory.

In your case, you seem to be using

        "pettoct"

as output directory. Please make sure
that you create this subdirectory in
the place where you are running your
program.

For example, if you are running it on

      /home/nay/itkdata

create the directory

      /home/nay/itkdata/pettoct

The application will not attempt to
create the directory for you.

Hope that helps,



   Luis
