[Insight-users] problem in execute example in "Getting Started with ITK + VTK"

[Luis Ibanez]

HI Knoppix,

Thanks for the detailed description of your problem.

Please note that the error message that you get is also very clear:

             "FileName must be specified ""

It seems that your program is expecting the filename of the input
image as the first command line argument:

              reader->SetFileName( argv[1] );


and you probably are not passing any filename in the command
line, or you may be trying to execute the program by just double
clicking on its icon from a file browser.


You should execute your program from the command line
with an expression like:

       myprogram.exe   BrainProtonDensitySlice.png


The BrainSlice images are in the ITK directory:

            Insight/Examples/Data



  Regards,


       Luis
