<div>Hi</div>
<div> </div>
<div>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
?</div>

<div><span>Hello,</span></div>
<div><br><span></span></div>
<div><span>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:</span></div>
<div><span><br></span></div>
<div>********************************************<br><span></span></div>
<div><span>Requested region is (at least partially) outside the largest possible
region</span></div>
<div>********************************************</div>
<div> </div>
<div><br><span></span></div>
<div><span>I've already used "UpdateLargestPossibleRegion()" method, here is the
partial code:</span></div>
<div><span><br></span></div>
<div>********************************************<br><span></span></div>
<div><span>reader->SetFileName(argv[1]);<br>
reader->Update();<br>
reader->UpdateLargestPossibleRegion();</span></div>
<div><br><span></span></div>
<div><span> ImageType::RegionType desiredRegion;<br>
desiredRegion.SetSize(size);<br>
desiredRegion.SetIndex(start);<br> <br>
filter->SetRegionOfInterest(desiredRegion);<br>
filter->SetInput(reader->GetOutput());<br><br> WriterType::Pointer
writer = WriterType::New();<br> writer->SetFileName ( argv[2]
);<br> writer->SetInput ( filter->GetOutput() );<br>
writer->Update();</span></div>
<div>********************************************<br><span></span></div>
<div><br><span></span></div>
<div><span>Can anyone help? Thanks in advance. </span></div>
