Hello Rupinder, <br><br>Could it be that your CastFilter's output is of OutputImageType <br>and your Writer's input is of InputImageType and you connect<br>the cast filter's output to the writer filter ? Templating the ImageFileWriter<br>
over the OutputImageType might solve your problem. That is instead of<br><font style="font-size: 11px;" color="#2d2cfa"> typedef itk::ImageFileWriter< InputImageType > WriterType;<br></font>try <br><font style="font-size: 11px;" color="#2d2cfa">typedef itk::ImageFileWriter< OutputImageType > WriterType;<br>
</font><br>PS. You can attach the error to the email for a better diagnosis.<br><br>Regards, <br>Cagatay<br><br><div class="gmail_quote">On Mon, Oct 31, 2011 at 10:03 PM, Rupinder Singh <span dir="ltr"><<a href="mailto:rupinder.singh123@yahoo.com">rupinder.singh123@yahoo.com</a>></span> wrote:<br>
