Dear Brian and Arthur,

 

I am running into problems trying to run simple bivariate models and wonder whether it is because it is the first time I am using ASReml3. This is a study of 3742 records of laying date (LD) and arrival date from migration (AD). We have some missing records, but 3130 records with LD, AD and sex known (we are using MVREMOVE to restrict to these records).

 

Here is the simple first model we are trying to run.

- With ASReml1, I would have used the following syntax:

 

#############################################################

 

AD LD ~ Trait Trait.SEX

 

1 2 0

0

Trait 0 US

3 * 0

 

- Using the new ASReml3, we have used your user guide to rewrite the code as (although the guide says the previous is equivalent):

AD LD ~ Trait Trait.SEX

 

1 2 0

0 0 ID

Trait 0 US

3 * 0

 

Running both these models with ASReml2, we get the conclusion error message of “structures are wrong size”. The intermediate message is:

Error structures imply 7364 data cells but the data has 7365

 Fault 1 Error structures are wrong size

Running them with ASReml3, we get an error message with unfinished sentence:

“Warning: Dropped records were not evenly distributed across the”.

I have a feeling this could be linked to the redundancy in residual variances that appeared with ASReml2, that we dealt with using !S2==1, but here iterations do not even start..

 

Best wishes for Christmas and the New Year to all ASReml users,

Anne
