<p><font size="2">Hello Kishore,<br>
<br>
I downloaded the latest CVS version. When I run my program it always fails in a specific place: itkMultiphaseSparseFiniteDifferenceImageFilter.txx, UpdateActiveLayerValues function, line 508, reporting the following error:"vector subscript out of range". It seems to me that m_PixelDistance is a 6-dimensional array and it tries to get m_PixelDistance[6], that is a non accurate position. Could it be possible to check if you have the same problem?<br>
Thanks again for your time and help.<br>
<br>

Hi Eleni,<br>
<br>
The RMS change values are now computed after reinitialization to signed<br>
distance functions. So, it will now show up as small values. Remember to<br>
download the latest CVS version.<br>
