[Insight-users] Bug in ITK's FRPR optimizer

[Tom Vercauteren]

Dear Alvaro,

If I remember correctly, this bug was fixed a while ago:
http://public.kitware.com/Bug/view.php?id=4827

Are you using an up to date version of ITK?

If so, this might be a different one... Anyhow, please keep such
discussions on the ITK mailing list.

Hope this helps,
Tom
