Yes, sorry. I sent another email with the proper format shortly thereafter. Sorry for the noise.

Dear Jared,
thanks for your question !
Your question seems to drift apart from the one that started this
thread or the subject of this thread.
In order to increase the chances of it getting answered, could please
post your question on a different thread?
Please, read our community discussion guidelines, especially the "Keep
tidy" section:
https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fdiscourse.itk.org%2Fguidelines&data=01%7C01%7CJared.Becksfort%40stjude.org%7C2070d2bf4b7944b95bb308d564937a1b%7C22340fa892264871b677d3b3e377af72%7C0&sdata=xPacI3N%2B2bxM6VjGt5o%2Be7JQjrd7fAtQS12nDxDmdWk%3D&reserved=0
Also, providing a minimal, compilable code snippet (either through a
GitHub gist) or by attaching your own files reproducing the issue
(.cxx files, CMakeLists.txt, your own input data, etc.) would help.
Note that we are transitioning from this mailing list to discourse:
https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fdiscourse.itk.org&data=01%7C01%7CJared.Becksfort%40stjude.org%7C2070d2bf4b7944b95bb308d564937a1b%7C22340fa892264871b677d3b3e377af72%7C0&sdata=Ml2KzsOGytZ5ylV9khEWD0rs3QA89TRY2W8IWdCO8tw%3D&reserved=0
So we'd be grateful if you could post your question there taking into
account the above.
Cheers,
JON HAITZ
