[Insight-users] Exception in groupwise registration code

[Xi Liang]

Hi,

I am running the groupwise registration code submitted in Insight
Journal http://www.insight-journal.org/browse/publication/173

I build the code using ITK 2.8.1 (with VS2009) as suggested in the
documentation since it is not compatible with ITK4.0. I came across
the following complains about the multi-threads. Do you have any idea
what this message is about?
