[ITK] [ITK-users] cannot acces virtual void itk::Rigid3DTransform< TScalar >::SetMatrix (const MatrixType & matrix, double tolerance ) from the Rigid3D transform class.

[Matt McCormick]

Hi Yago,

The tolerance parameter was added in a very recent version of ITK.
Make sure you are using the latest version of ITK.

HTH,
Matt
