Hi everyone: I am trying to work with the ASREML PC version. I have a model with more than 400 levels for fixed effects and the program give me the next message: Too BIG! Use -s option. I have used -s6 option and the message is the same. Could somebody help me? Thank you very much. -- Asreml mailinglist archive: http://www.chiswick.anprod.csiro.au/lists/asreml
