Hello,

Thanks for the answer, now it works after I set its start index to [0,25,0].

Hi

According 
to your code. Your start index and size is same. You had replaced with inSize 
variable.. ? I donot think it makes any sense.  

Your index 
should like (0,0,0) and size should (220,225,144).

  Hi Alex and John, 

Thank you so much for your answers. I did use the 
itkRegionOfInterestImageFilter. And here is my code:

****************************
  start[0] = inSize[0];
  start[1] = inSize[1];

start[2] = inSize[2];

  size[0] = inSize[0];
  size[1] = inSize[1]/1.162;

size[2] = inSize[2];

  desiredRegion.SetSize(size);

desiredRegion.SetIndex(start);

filter->SetRegionOfInterest(desiredRegion);
filter->SetInput(reader->GetOutput());
*****************************

I doubt its starting point is causing the problem, but I didn't figure out 
any solution yet. I tried to change it, but it was not helpful. 

Thanks.

Hi

I think it’s in range. Can you show your code ? what exactly you trying to 
do ? After reading file are you using any filter and then doing ROI filter 
?

  Hello,

The size of input image is [220, 250, 144], and that of ROI image is 
[220,225,144]. 

Any suggestion?

Thanks :)

  Hello,

Actually I found that I can handle this problem by using 
itkRegionOfInterestImageFiler, it works quite well, except it started to 
truncate the image from the opposite of the desired direction. Then I tried to 
set its index, but it gave me this error:

********************************************

Requested region is (at least partially) outside the largest possible 
region
********************************************

I've already used "UpdateLargestPossibleRegion()" method, here is the 
partial code:

********************************************

reader->SetFileName(argv[1]);

reader->Update();

reader->UpdateLargestPossibleRegion();

  ImageType::RegionType desiredRegion;

desiredRegion.SetSize(size);

desiredRegion.SetIndex(start);

filter->SetRegionOfInterest(desiredRegion);

filter->SetInput(reader->GetOutput());

  WriterType::Pointer 
writer = WriterType::New();
  writer->SetFileName ( argv[2] 
);
  writer->SetInput ( filter->GetOutput() );

writer->Update();
********************************************

Can anyone help? Thanks in advance.

Hi,

I 
didn't find any way to do that as you suggested. Seems like there is
no way 
to set the index for the itkImageWriter. Am I doing 
wrong?

Read the 
series and then write it truncated.
