<HTML><BODY style="word-wrap: break-word; -khtml-nbsp-mode: space; -khtml-line-break: after-white-space; "><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><FONT class="Apple-style-span" face="Monaco">I am trying to output post-processed data that preserves most of the DICOM metadata from the input DICOM files, but with a few fields modified. Unfortunately, while the data itself is output and appears correct, I can't seem to get ITK to include anything but what I guess is the default GDCM DICOM stuff. A snippet of the code that I'm using (InputType is Image<float,3>, OutputType is Image<short,3>) is below. The dumpITKMetadata function just prints all the tag/value pairs to std::cout - in this case, the first call includes altered/added fields, so my changes are propagating correctly into the gdcmImageIO variable, but don't seem to make it the rest of the way through the pipeline. Any suggestions on what I may be doing wrong?</FONT></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><FONT class="Apple-style-span" face="Monaco"><BR class="khtml-block-placeholder"></FONT></DIV><DIV style="margin-top: 0px;
