Resuming iteration


!CONTINUE is used to restart/resume iterations from the point reached in a previous run. This qualifier can alternately be set from the command line using the option letters C (continue) or F (final) options the top job control line using !CONTINUE or !FINAL.

After each iteration, ASReml writes the current values of the variance parameters to a file with extension .rsv (re-start values) with information to identify individual variance parameters. The !CONTINUE qualifier causes ASReml to scan the .rsv file for parameter values related to the current model replacing the values obtained from the .as file before iteration resumes. If the model has changed, ASReml will pick up the values it recognises as being for the same terms. Furthermore, ASReml will use estimates in the .rsv file for certain models to provide starting values for certain more general models, inserting reasonable defaults where necessary. The transitions recognised are
  • DIAG to FA1
  • DIAG to CORUH (uniform heterogeneous)
  • CORUH to FA1
  • FA i to FA i+1
  • FA i to CORGH (full heterogeneous)
  • FA i to US (full heterogeneous)
  • CORGH (heterogeneous) to US
