<div style="direction:ltr; font-family:Tahoma; color:#000000; font-size:10pt">Hi,<br>
<br>
After some search through the older blogs, I was able to fix the issue by using UpdateLargestPossibleRegion() instead of update in the extract image filter and the other filters following extract image filter.
<br>
<br>

Hi,<br>
<br>
I am trying to extract a slice in the x and y direction other than the z direction. Initially the direction is set to "z" and then the direction is set to "x". The code works fine for "z" direction but when I set the direction to "x", I get an error<br>
as below<br>
<br>
<span style="color:rgb(255,0,0)">Requested region is (at least partially outside the largest possible region.<br>
<br>
<span style="color:rgb(0,0,0)">Kindly let me know what I have done wrong. Pl. find the code snippet below. The code is called iteratively for the same MR data.<br>
<br>
</span></span> <span style="color:rgb(255,0,0)"><span style="color:rgb(0,0,0)">size = inputRegion.GetSize();<br>
start = inputRegion.GetIndex();<br>
<br>
size[direction] = 0;<br>
start[direction] = number;<br>
<br>
<br>
//Now set the parametrs to the extract the desired region<br>
//the parameters are size and slice number<br>
InputImageType::RegionType desiredRegion;<br>
desiredRegion.SetSize( size );<br>
desiredRegion.SetIndex( start );<br>
<br>
filter->SetExtractionRegion( desiredRegion );<br>
filter->SetInput( output );<br>
filter->Update();<br>
</span></span></div>
