Ok!
the script and the image are in the directory d:\
the image is a .tif

In IDL command line I typed the calling sequence with those
parameters:

Result = sigma_filter( image.tif, 5, 2 )

I want the box_widht to be of 5 and the N_sigma to be 2.

The error i got is:

% Syntax error.
IDL> Result = sigma_filter( image.tif, 5, 2 )
% Expression must be a structure in this context: IMAGE.
% Execution halted at: $MAIN$

If try to show the path of the image like d:\\image.tif the error
message is:
% Illegal character in program text.

Thank you for your help,
Max
