Re: Multiple trait model-covariate for one trait only



IMPORTANT NOTICE

I have just discovered an important bug in setting up the design matrix
for certain interactions  - mainly  interactions of constrained terms
like c(A).c(B) are affected.  The bug will not affect variance components
but does mess up the interpretation of the constrained fixed effects.
It has not altered any of my test jobs.

If you have predicted means from an analysis with interactions of constrained
terms, you should rerun the job and recalculate the predicted values.

I hope to put a fixed version up later today and will advise.

Please accept my sincerest apology.

===========================

Concerning HUGO's question
 

Assuming you have the data in the multivariate form,
 e.g.
 
 Header
   tag !P
   sire
   dam
   fix
   x1
   y1 y2 y3 y4
   
  data_file
   y1 y2 y3 y4 ~ Trait  at(Trait,1).x1  Tr.fix !r Tr.tag
   
   etc
   
   
   
 If you have an older version,  use  Trait|1/x1  instead of   at(Trait,1).x1
