I've seen an error like "No conversion available from 5 components to: 5
components." when accidentally trying to pass a itk::Vector<float,5> as a
itk::Vector<unsigned char,5>. The error should definitely say something
about the type (5 to 5 doesn't sound like anything is wrong). I'm not sure
where this is happening for you though.
