[Insight-users] Exception thrown while reading a cropped file !

[Luis Ibanez]

Hi Juliette,


1) What File Format are you using ?

2) It looks that you are you reusing a reader class instance,
    that you have used before for reading a previous image in
    your program. Presumably the same reader that you used
    for loading the input image that you cropped.

3) It is ok to reuse a reader, but, when you do so, instead
    of calling

                         "reader->Update()"

     you must call the method

                    "reader->UpdateLargestPossibleRegion()"


    in order to trigger the recomputation of the regions to be read.



  Please let us know how it goes.


    Thanks


         Luis
