[Insight-users] error while extracting slice in x and y direction

[Jayachandran, Ganesh]

Hi,

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
as below

Requested region is (at least partially outside the largest possible region.

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.

    size = inputRegion.GetSize();
    start = inputRegion.GetIndex();

    size[direction] = 0;
    start[direction] = number;


    //Now set the parametrs to the extract the desired region
    //the parameters are size and slice number
    InputImageType::RegionType desiredRegion;
    desiredRegion.SetSize( size );
    desiredRegion.SetIndex( start );

    filter->SetExtractionRegion( desiredRegion );
    filter->SetInput( output );
    filter->Update();
