My apologies..<br><br>It is a VS window that pops up with the following message:<br><br>///<br>Debug Assertion Failed!<br><br>Program: Deformable Registration<br>File: f:\dd\vctools\crt_bld\self_x86\crt\src\strtol.c<br>Line: 94<br>
<br>Expression: nptr != NULL<br><br>///<br><br>I am not even sure if this error is specific to VS, or what assignments I am making in my modified code that would yield a successful debug-build, but yield a runtime assertion error?<br>
<br>Thanks again,<br><br>Tim<br><br><br><br><div class="gmail_quote">On Tue, Mar 20, 2012 at 10:00 AM, Bill Lorensen <span dir="ltr"><<a href="mailto:bill.lorensen@gmail.com">bill.lorensen@gmail.com</a>></span> wrote:<br>
