Dear Marcelo,

I understand (from off list emails) that the problem was that the .grm file was not positive definite.
You resolved the problem by using the !NSD option in ASReml 3.

Off list I wrote

1) Let's try something simple first.

  Increase the WORKSPACE
i.e. insert a new line at the top of the .as file which says (say)


and rerun the job.

2) If that results in it failing at exactly the same point,
it suggests a problem with the file. But you could swap the order of
the .grm files and see whether that makes a difference.

3) Third option is to use ASReml 3 (from
if not available yet from VSN)
